I pulled the front seats out of my 89 IROC today and found a 8.5 by 11 in piece of paper. Not sure what it is. I can read the larger print, but i cannot read the smaller print. Could anyone else who has found this post a pic so i can figure out what it says. Where can i find out what the codes mean?

Thanks

 

Its a buildsheet... do a search.

 

Damn I need to get off my a$$ as look for my build sheet.....

 

You just had a good find.

 

After reading this post I reached up under my front seat and pulled out my build sheet. It didn't tell me anything I didn't already know about the car. The codes: only an employee of GM would know what they mean.

87 IROC
305 tpi
auto
g92
t-tops
leather
option level #2

 

Three books that will dicifer(can't spell) all codes:Camaro white book 1967-1997, Illustrated Camaro Buyers Guide, and the shop manual for your specific year(This book is about 3 1/2 in thick) first two books will also give you "how many" on alot of ****

 

have you seen a build sheet? they typically have a few RPO codes that can be decoded with books, then you've got about 3 times as many codes that aren't RPO codes, and they aren't in any books that are on bookstore shelves or in the white book.

 

yes, i have one from my car(92Z28) the top of the sheet must be what you are talking about.

 

Hey all i just want to know where it is. Is it under the carpet or just on top of it

 

I found one of mine behind the passenger side door panel while i was replacing a burnt window motor.

 

Whats a build sheet.

 

i hear that you can find them under the carpet, under the seat, front and rear some cars have them other's don't. i suggest you look for yours. a build sheet authenticates, what your car is. what options it came with . it can actually add a few thousand dollars to a rare car. it also tells what dealership your car was sold from. if your looking to restore a car, it is the most valuable asset in your restoration.

 

by the way drew, again a build sheet authenticates what you have. you CAN dicipher enough of the codes to tell you every option that your camaro came with. a built sheet is not that hard to figure out.

 

Here's the one I found under my seat. Some of the codes are RPO, but I don't know what alot of the other codes mean.

 

Ok then, start with labrat's build sheet...

Identify the following to prove me wrong...
AY, AD, NC, FX, BR, TK, JL, AC, YA, YM, ETC.

if you can find a resource that decodes those GM codes, then you're right, if you can't then I'm right.


You said "Three books that will dicifer(can't spell) all codes..."

I said "they typically have a few RPO codes that can be decoded with books, then you've got about 3 times as many codes that aren't RPO codes, and they aren't in any books that are on bookstore shelves or in the white book."

So what part of my statement was incorrect?

Oh, and for all the buildsheet questions, https://www.thirdgen.org/techbb2/sho...threadid=93722
Obviously no one reads what I consider to be required reading for participation on this board...

Whats a build sheet and where do I find it?

The build sheet or sheets, were print outs used in the actual assembly process of your car. As the car went down the assembly line, various build sheets were used to help the workers assemble your car to match the order. Some were adhesive backed and stuck to various subassemblies. Some were placed between the springs and foam in the seats. Some were placed under carpet or on top of the gastank. Some were tossed when the car arrived at the dealership and was prepped for sale. Some weren't left in the cars at all. The information contained on the buildsheets is hit and miss as they vary, but generally they don't include as much information as the RPO codes, and searches seldom ever find them.

 

Must be Drew.

 

that's the first build sheet i've seen that looks like that, would that even be considered a build sheet, most build sheets i've seen look very much like this:

 

sorry it's so small

 

I hope you dont have to say that to your girlfriend or wife!

 

knew i would get sh** for that

 

I've got a couple of different build sheets... the codes that can be deciphered are the typical RPO codes, the rest are codes that correspond with the tags on various components. For example the Master Cylinder is listed as XY, the master cylinder on the car will have a sticker with the letters XY on the front. Other listings are abbreviations. Regardless, if you've got the RPO sheet, the build sheet is rather useless and not worth searching for. They're nice to have, but they're better left inside the seats.

 

sorry drew i don't agree with you

 

Name one piece of important information contained on the build sheet that isn't contained in the vin or RPO's?

 

Just for fun...

Build sheet from my 83 Camaro...

 

Build sheet from an 88 Coupe...

 

So lets take a closer look... since the stains make these hard to read, you'll have to take my word for most of this... But..... lets start with the sheet from my 83.

Useful information... Well we've got a Vin number. Thats nice, its also on the car, so it doesn't really help us much. What else? we've got some RPO's, with definitions. These are nice since 82-83 fbodies didn't have SPID's stock, but if it had a label the sheet would save maybe a few minutes that would normally be spent with a book. Beyond that? a couple assembly line codes, that arent logged in any references, and finally a "bill to address", order number, etc. This is kinda nice since it shows why the car was built, but since dealers frequently trade cars, etc it doesn't really give us anything concrete to work with.

So if I had the VIN and the RPO codes this sheet would be rather redundant.

On to the 88 sheet.

What does it have that we can use... a Vin number... ok... again rather redundant. A couple RPO codes, notably the spring codes (redundant since the springs themselves have id labels. And, thats it...

Neither tells me anything I didn't already know about either car.

 

Well to answer part of the question...

My 86 did not have a RPO list, it was long gone. The dealer was no help either. I finally called Pontiac, they were able to dig up the dealer invoice on the car, and sent me a copy of that. Its for the most part complete, of course they dont list all that is on the RPO list. Later while working on the car (and I thought I had looked everywhere) I found the build sheet for the car hiding under the carpet by the gas tank. If Pontiac hadn't sent me that invoice, without the build sheet I would have had nothing to tell me what my RPO's were. Thats a reason to have or find one, I know I wanted mine since the list was gone.

 

I agree with Drew, the build sheet I found did not tell me anything that I didn't already know from my vin number, RPO codes and window sticker. Basically I should have left it under the seat. BUT I was curious

 

I know that a build sheet has the same info as the VIN and RPO label, that's a no brainer. that's not the issue. again.....it authenticates what you have, also lets say you don't have the label on the springs or master cylinder(after a few years of life on some cars they fall off) now it becomes a little less redundant. ask any classic car owner what a build sheet does for value to an original car. It's also a type of paper trail for a car, which is important for a true restoration. drew, looks like you figured out what the codes on your build sheets mean. which is pretty good, because by defending yourself through the last few post, you actually answered the orginal post that started all this.

HEY GUYS, I ACTUALLY GOT DREW TO ANSWER A QUESTION!!!!!!!! :lala:

Drew, I'm not trying to be a total dick here,but people come here and ask questions because they may be new to the scene or may not even know that they have books about these things. i understand that you are trying to keep things running smoothly by pointing them to the right resources, but some people may not have the right resouces(books). we have to help our brothers out. any info that you and i and other knowlegable people have my give them enough of a clue to figure out the other things that come simple to us. if you make it sound like your being bothered by these questions, people won't come looking here for the answers, which will make this forum very weak w/ info.

 

I just don't see the point in having 30 threads in the course of a month dealing with "whats a build sheet". There's no need for it. The answers to most questions have already been posted. People need to look before they post otherwise people like myself that have been around a while get tired of reading the same thing so we stop frequenting the board. By starting with whats already been posted we improve on what we already know and it keeps things interesting for everyone.

The misc tags and assembly codes aren't that big of a deal either since most thirdgens are pretty similar most of the codes are the same. Personally I take the time to bag and tag any part number labels, id tags, etc that come off the car while I'm cleaning. Some day if I choose to do a complete restoration I'll have them on hand to do it right.

 

Gents,
I know from reading this thread that I'm in severe danger of asking a really dumb question, and getting verbally blown away. I have ready the sticky at the top of the page, and visited many other sites in respect of RPO codes, but (please don't shoot me) I need some additional help. I have a build sheet from my '89 Camaro RS.....

1. Is there more than one build sheet to a car? I have one titled "Trim" but also includes the engine code.
2. camaroresource.ca does not show "1FP87" as an RS coupe on it's RPO list. so... I'd like these and two other questions answering :

3. Where do I find out how many '89 RS coupe 305, Auto, Air, etc. were built.
4. What is the RPO code hub cap=DCP? My RS does not wear any centre hub caps, but I've seen an '89 with a V6 that does. Should I have them?

Cheers,
Paul

 

RPO code 1fp87 is the code for all camaro models in 1989.

There can be no build sheets in a car, one, or multiple build sheets.

Gm didn't keep track of option combinations, there were 83,487 rs coupes built in 89.

Yes your car should have plastic center hub caps.

 

There are a few different "build" sheets for 3rd gen Camaros. The first type of sheet lists all the options on the bottom half . also on this sheet is Dealer info, date schedule of build, assembly codes exc. I see also on this thread there is another sheet shown, this is a sub-assembly line sheet, this sheet is usually for the different departments on the line, such as the trim line, the codes on this sheet are mostly assembly numbers or the last 2 digits of a part #. I bought 2 new 3rd gen Camaros, both had the build sheets and the sub-assy. sheet thrown on the floor at the Factory (Van Nuys). I also have a copy of a water test inspection/repair ticket that shows where a leak was found during a water test. Both plants used the more common build sheet with all the RPO's listed, but I have only seen the other in Van Nuys cars., Chris

 

THERE WERE 46,715 RS COUPES W/THE "LO3" 305 ENG IN 1989

 

Just a couple of points. I have never seen a RPO code that is anything but 3 digits. So I would venture to say that these 2 digit codes or 4 digit plus codes are not decodable RPO codes.

Also in order to have something authenticated. It needs to be worthy of being authentic. Although to me my 86 T/A is priceless I feel it will be many decades before the majority of our cars need authentication.

I have two examples recently of where this would be important. I am about to sell (for another party) a 1969 SS 396 Convertible. I will be digging all through the car to find the build sheet. The reason is because in 1969 the SS quit being a separate car line and became an option. Therefore from 69 on there are acutally more "clones" than actual SS's. Being able to validate whether or not this car is actual vs. clone, plus being a convertible could add thousands of dollars to the selling price.

Example 2 would be: We started working on an extremely low mileage 80 Trans Am Turbo Pace Car. There were only 5700 of these made. We came across the build sheet a couple of days ago. Now especially with places like Phoenix Graphix, a good upholstery shop, and body shop it would not be too hard to clone this pace car. Another decade or two and the build sheet on this car could become an important factor as more and more of these originals vanish.

 

i agree. nicely put.:hail:

 

Example 2 would be confirmed with an "X" in the 2nd digit and a "T" in the 5th of the Vin number.

 

Yes 85. Didn't know that. But in the case of example one there are people counterfeiting vin tags, cowl tags, data plates, and even restamping engine blocks to "clone" these cars. Or they are robbing them from parts cars and reconstructing.

Someday it may happen to the elite of most valuable of 3rd gens too.

BTW I never paid much attention to the 80 Pace car but geeeeeeeeeeeezzzz this is a nice car.

 

Mike,

I have my eye on a 1980 pace car now, so it helps to know little details like this.
345 ft lbs of torque at an ultra-low 2000 rpm from a lil 301 is hard to imagine ! The chance of owning one of the last V-8s that PMD made would me nice

The cloning has me concerned, people are paying big money for cloned muscle cars now and it encourages what you described.

Don

 

Don,


I hope it comes through for you. I am SO impressed with this car. The interior, the white wheels, the engine, this is one cool ride. If it would help you, we found the build sheet under the rear seat.

Also I scanned it to which you are welcome to a copy of the image in the future if you wish (minus the VIN of course) as I believe they were all identical (?).

 

Where would the build sheet be on a 1985 IROC Z camaro.
Please Help me find mine.

Thanks

 

Iroc you might try doing a search and look for where other 85 owners found their sheets. They are really in no specific place. Under the rear seats, in the front seat springs, inside the door panels sometimes even under the carpet.

Some cars don't even have build sheets and others have the wrong sheets or the sheets of several cars thrown in. I would stick your hand up under the front seats and check the springs and maybe take out the back seat cushion as that is not too hard.

Other than that it is almost by mistake to find it.

 

I stumbled on mine last weekend when I ripped out the carpet. It was under the carpet, under the drivers seat stuck to the black stuff. neato.

 

Well, I learned something new about my car after reading this post yesterday. I didn't know it came with a build sheet so I went hunting and went to the passenger seat and no luck. I went next to the drivers seat and I struck gold with my first build sheet for the 1986 Z28.

I think I am just going to leave the cars build sheet in its place.

Thanks to everyone who wrote on this thread about there build sheet or the information that helped me find one of mine. Picture enclosed of under drivers seat.

Chet

 

MikeInAZ - It's very easy to decode a 69 SS without the buildsheet or POP. The only thing that paper will do in your case, will make it easier for the buyer to see what they are getting without climbing under the car. The cars are easily detectable based on engine block castings and the limited possibility of the X codes. I recently decoded an RS/SS 350 for friend just to find out the block casting was correctly date coded to the car, but was not coded for an SS. This left the car being only an RS. The seller wasn't happy, but now he also knew what he had and had to price adjust accordingly.


I agree with Drew to the extent that it is just paper. The only value it will have, is for those of us with bone stock cars looking for the ultimate in documentation on their cars. Replace your springs or master cylinder with an aftermarket and now this information is worthless as to what's on the car. It will authenticate my car as original someday, but does nothing for it's value now. It will only prove that the options on my car, came from the factory that way and weren't added by me.

Well Ive done extensive searches on this build sheet subject, and through my quest for info about my 89 GTA I learned the only RPO listing other than the build sheets was the SPI label (is that correct) mines history and with the 89's I guess your screwed if they are missing and you want to authenicate, the only other means to authenicate are PHS or maybe these build sheets which Im hoping to find them.. without PHS or these buildsheets its awfully hard to prove my car is an authentic GTA.

 

Based on the VIN alone, here the breakdown.

VIN NO. 136679K395373
1 - Chevrolet
36 - Malibu or Custom El Camino (V8)
67 - 2 door convertible
9 - 1969
K - Leeds, Missouri (build plant)
3 - 1969 and up
95373 - build sequence.

Block SN matches the VIN.
head number = 1969 396 325 350 2.06/1.72 (int/ex) 100.967 (cc)
The block was built in December, the 10th day of 1968.
block cast number = #3955272 (SS) 1968 396 325, 350 2-bolt or a 375 4-bolt

Engine Suffix code - Tonowanda built on Jan 12th, 396 with manual trans.

Tranny - M20 68-69 3925660 2.52 1.88 1.46 1.00 muncie 4 speed.

Rear axle stamp appears to be a numbers match for date codes

The car should be glacier blue with black vinyl bench seats.

This car is a true SS 396, not a clone!
