Hey okfoz, the stock springs on my car have a number on them, ill try and take a pic of the fronts since i painted the rears.

 

There is usually a sticker on each of the springs that has an RPO and a part number...

 

Here is my 1985 IROC LB9 California emissions lable.

 

hi everyone,i have a 84 camaro z28.the hood has black stickers where the louvers go.my question is,will the louvers from a 85 to 92 iroc fit on my hood? is there any differance in size?

 

On the first picture, where it says "UNJ" on the upper left hand sticker, I think that denotes what prom chip is in the ECM. Does anybody know if thats correct?

 

Here is the spring tag on the rear of my 85 IROC LB9 A4. it has NNN and the part number.

 

thats what mine looked like! to bad i sanded and painted them before i got a pic

 

i posted this question awhile back ,guess nobody has a answer,i guess i'll have to go to a chevy dealer to get an answer.

 

The 82-84 hood is different than the louvered hoods. You cannot install the louvers on an 84 hood. You need to locate an 85-92 Z28 hood.

 

To add to what scott said.. I want to think that the area on the 82-84 style hood was narrower than the 85-90 style hood... So as Scott stated you would need a different hood for them to work correctly...

thanks for the info,I may just keep what i have.

 

thanks again,i have the car ready to get painted,so i'll just stay with what i have,thanks.

The UNJ on that label is the "Label Code"
The second line is the "Engine Size"
The third line is the "Exhaust Emission Family"
The fourth line is the "Evaporative Emission Family"

The above is from the 1982 Camaro Service Manual, Fig 6E1-1 "Vehicle Emission Control Information Label"

The ECM prom type is on the ECM label. Below is the ECM from an 82 CFI car, with Engine Code 7.

The ASY in the upper left corner is the prom code in this ECM. I have a photo of the electronics on the inside, but you can barely make out the ASY on the prom due to flash washout. The Prom is the chip in teh top center of the photo.

bestracing,
thanks... I will be honest, there is no exact location, the factory had a rough placement for the decals and that was close enough. But what you have given is beneficial. Thanks.

It should also be noted that typically the Trans Am decals on the front and rear bumpers were typically lower without the stripe....

Thanks again.

John

 

At least it will get people in the ball park

I have some OEM supension stuff on my 86 that still has the stickers. I just have to remember to get pics of it when I'm under there again to fix up the rear housing this winter. I won't forget....

 

Bestracing....Do you still have the measurements of the decal locations for the sail and the nose stickers? I tried to see from your pictures but could not make some out. I just painted my 89 firebird and wanted to redecal it. Thanks for your help!

 

Sticker on driver side rear shock of my 1985 IROC with NNN springs.

 

I notice the little sticker on my 85 says change spark plug gap to .35. When and why was it changed? Was it changed in all states or just california?

 

pic.

 

https://www.thirdgen.org/forums/atta...n-sticker2.jpg here is a bigger pic. It says The spark plug gap has been changed to 0.035 inches per chevrolet campaign bulletin number 85-c-22

 

I think I found the answere in the Chevrolet Dealer service bulletin # 85-93 section 6. june 1985. High output ignition coil replacement.

 

Sorry I haven't checked this out lately but yes I do have the numbers. Once I get home to my computer I'll post them up. The original pictures are huge so I had no problems seeing them but didn't look back at it after resizing them.

 

Nose is 1 7/8" from hood edge

Sail panel is 3 1/4" from the window edge and ~1 3/8" up from the body line to the line on the bird.

 

Here are some from 1991 Firehawk #003, 1,24x original miles at the time I took the pictures...

 

More...

 

and more...

 

and the last.

I have a TON more however they are of chalk marks, paint marks, all kinds of build marks, especially of the suspension, and aren't really decals so I won't post them here.

 

and here are some from my 92 GTA...

 

more...

 

more and more...

 

Still going...

 

and finally.

These were all taken about 10 years ago when she had 69K miles.

 

Can anybody tell me the correct decal for the rear bumber on a 89 GTA ? I've gotten different answers.

One answer was the "5.7 tune port injection" medalion in gold located on the drivers side.

Another was "Pontiac GTA" decal in gold located on the passenger side.

Or did they come off the assmbly line with any at all ?

So much aftermarket crap !!!


Thanks in advance

 

What's a bumber?

 

There was no "5.7 Tuned Port Injection" badge on the GTA. There also was no badges or emblems on the GTA's bumper. It's the Trans AMs that would come with "Trans AM" scripts written on the bumpers, and on the driver doors for the later Third Gen Trans Ams. It's also the Trans AMs that would (at times) advertise engine size on the fender. This wasn't on the GTA.

Pontiac should be embossed in the center of the rear bumper on your 1989. That's all that's on the rear bumper of the GTA.

For 1989, you should have two sail panel badges (one per sail panel):


You should have two GTA emblems on the fender (one per fender):


You should have one, metal, badge on the front bumper in the center:


You should also have one Pontiac, in gold lettering, script on the driver's side headlamp door:


Finally, you should have one emblem, in gold, in the center of the tail lamps :



Thanks to Frankie's GTA Source Page website for the images above.

 

Excuse me members for not calling the rear bumper by the correct description.


Thanks for the info and the pics JT...I assumed such, just needed some verification from the board..I come to this site for advice from knowledgeable experts like you all on these cars, and I take that advice seriously..

Again thanks...



As for Jeff....Back at ya...Everybody likes a little a$$, but nobody likes a smart a$$..

I have a lot more but I'll need to locate the pics.

 

Does anyone have measurements for the door and bumper FORMULA decals and the hood engine call-out ones? Thanks.

 

If you have original decals, the paper properly locates the decal on the hood and doors.
The door decals are high/low depending on stripe/ no stripe and how the installer felt that day.
F/R bumpers were on the right side (as looking at them) I know on the rear bumper the end of the formula decal ends around about straight down from where the decklid/quarter gap is. I think the front bumper formula decal is about the same with the hood/fender gap.
Sail panel birds are also all over the place.
Front bumper bird has a locating paper backing.

I think the service manual may also have measurements of the correct location.

 

I don't believe there is an exact measurement...

Tony is right about the doors... The non stripe cars seem to be lower, but my Formula 350 Convertible is definitely higher on the door than I prefer. I go by the rule of thirds... It is where they look the best, After I painted mine I took the decals and I taped them to the door... I moved them up.. and down, until they looked right...

I think have measurements written down somewhere, but I might not be able to find my book.

The front and rear bumpers, is true to what Tony said...

The front bird should be in the center of the facia

Edit 2:
IIRC The sail panel birds are something like 2.75 behind the window highlight line to the wing, and 2.75" above the quarter highlight line roll to the tail feathers
