Found it. It looks like it depends on what RPO codes you have. Here are the pics I scanned so you can print them and compare to what you have.

 

25036979

Here is the caption that it says next to the part number:

Engine coolant Temp. (At intake manifold)(interfaces with ECM)(Used for clusters with oil gage & light combo)(goes with 12101899 connector)(2 blade terminal)( 3/8-18 threads)

 

Thanks. Thats just what I needed.

 

Thanks

 

hey Josh Man why dont You drop a stick on this ?

 

what do you mean 'drop a stick on this'? You mean close the thread? Why? I am not the one bringing it back, the people that want part numbers are. I am just providing this service for the hell of it. Ok?

 

I didnt mean lock it I was asking you To make this Thread Sticky Im sorry for any Mis Implication i sent off I was saying it was Really usefull.

 

My bad, i didnt know what you were saying....i shouldnt have jumped all over ya, like i said my bad. I never really thought of making it a sticky...but i suppose i could.....

 

Yay !

 

Specifically for a 1987 Firebird 2.8L V6, which is the donor housing.

I am doing the SLP posi thing with 90-92 axles, and I'm to the point where I am puting the brake system together and buttoning everything back up.

I need to know if the part numbers are the same with a 1986 Firebird ... parts man says there's 2 versions... metric thread and U.S. pipe thread.... and I need to reuse my 86 metal lines on the 1987 donor housing. I know between 1986 and 1987 GM changed a lot of stuff between those two years with tooling, shifting production to different plants, etc.

Oh, and a part number to cross reference a pinion seal as well.

Thanks a ton!!

 

OK I found out what one you need. It depends on one of your RPO codes. GM used different threads depending on the ring gear diameter of the rear axle. They say that you want to use P/N 18012304 if you have the RPO code Y03. If you don’t have the Y03 code, then use 18012303. The cylinder used with the Y03 code has the metric threads while the cylinder used w/o the Y03 code used standard US pipe threads.

Here is the info right from the book so you can know the years they were used too:

1982-1988 P/N-18012303 (W/O RPO Y03) Wheel Cylinder, Rear Wheel -Standard US Pipe threads
1984-1992 P/N-18012304 (W/RPO Y03) Wheel Cylinder, Rear Wheel - Metric threads

BTW, the definition of the Y03 RPO code is: 7.625” Diameter Ring Gear, Saginaw rear axle.

So as long as the housing’s are both from cars with the same RPO code of Y03 then you should be good.

As far as the pinion seal, if you are referring to the seal behind the slip yoke and it front of the pinion gear bearing, then here are the part numbers:

1982-1984……………….....………….............….….552571
1985-1992 w/7.625” ring gear……………...552571
1985-1992 w/7.750” ring gear……..……10112663

Josh,
Need Part #s for the following t-5 parts, 90-92, the numbers I have for them are not valid. I have attached the picture with the description. 26 - Dust/inspection cover for manual t-5 V8
29- Lower boot for shifter.

Thanks
Tom

 

Inspection cover- what exact year of car is this for?

And for the boot, do you need the upper or lower? or both?

 

90 firebird

lower boot

 

lower boot P/N=14105644 $20.60 at gmpd

cover P/N=14036055...assuming that you have the MB1 RPO code...N/A at gmpd

 

I have RPO mk6 Not MB1 (MB1 is v6 not V8)

Thanks Tom

 

OK sorry bout that, it's 14073767.

 

Josh, come to find out that that # is discontuned, Got new number for v8 with t5 that is valid for those that might want to know it is 10241153... about $5.60 at dealers.

 

I got one for you: I need the catalytic convertor hanger that bolts onto the tranny for it's support and I have no idea on the P/N. It bolts in between the tranny and the cat's flange.

 

I won't be able to get back to you until tomorrow afternoon. I won't be home to look at the book....but if you can wait til then I'll be more than happy to look it up for ya.

-Josh

 

Can I get the part #'s for the I 88 special appearnce package front and rear wheel "flares". I think GM called the Spats. here is a link to thread w/ a pick.


https://www.thirdgen.org/techbb2/sho...hreadid=199624

:hail: Keep up the good work :hail: Your help is appreciated....

 

Maverick H1L - What year is your firebird? Also what RPO is your engine? Dual or single cat?

87F383 - I found that special appearence package (RPO code Z20) with the P/N's for all of thise pieces:

Obviously all parts are prime and paint to match.

Spoiler - 12396621
Front wheel RH spat - 12396612
Front wheel LH spat - 12396613
Rear wheel RH spat - 12396614
Rear wheel LH spat - 12396615

GM says all of these part numbers are no longer in use and were discontinued between January of 1995 and March of 1995.

Sorry man but you will have to try to find these parts elsewhere. You also may want to try to call a local Pontiac dealer and ask them if they can get any older parts in or has a certain supplier where they can get them

-Josh

 

 

87 with the 700R4 and the LB8. Single cat on passenger side.

 

10026086 - hanger

& the screws are 11504596 (M10x1.5x25)

 

So are you going to start charging ppl here to look up some stuff? lol That book rocks man!

 

I was wondering if you could find the P/N for the 9-bolt diff. cover.

 

I know it may not matter, but humor me and let me know what year, motor, and car this is.

Thanks

 

It is a 1986 Trans Am, LB9(305 TPI), with a 700R4 Tranny.

Oh, and also could you find the P/N's for all the parts associated with the third brake light that sits on the hatch glass.

Thanks.

 

Ok I have the #'s for ya....

9-bolt Diff. cover w/7.75" ring gear - 10033563

For the high mount stop lamp...

Lamp - 918552
Screws (2 required) - 20676548

 

Thank you.

I keep on finding more stuff I need P/N's for... Could you find the number for the like... plastic gasket thing that goes between the side view mirrors and the door. And possibly the bolts/nuts? I appreciate it.

 

Can you find me the P/N for a Fuel Sending Unit (FSU) off of an 87 IROC , 350 5.7 TPI

 

JR86-TA....

The 'bolts' are attached to the mirror housing itself...therefore there is no p/n for the 'bolts'. However, the part numbers for the 2 nuts is 11508277. The gasket #'s are 20364442 (RH) & 12337844 (LH).

omnipotentgoku....

I assume that it mounts in the tank (on the tank)...I'm seeing 2 different #'s here for this. It says for the 'FUEL TANK SENDER' for 1987 cars with V8 (LG4/305G,H,L98/5.7-8) then the # is 25090906. It also says that the fuel sender assembly is N/A to purchase as a whole unit (I dunno why)

If it is also known as a 'FUEL SENDER PULSATOR' then the # is 25094266.

I dunno if this helps you or not, but if you want I can scan the pages and email them to you or post them here. Let me know.

Josh

 

P/N for Firebird radio pod is needed. Just the pod, without the heater vents. I have mine sitting in my lap at current and the numbers don't match GM PartsDirect.com, and the pod has two numbers, one for the vents and one for the actual pod.

 

The pod is 10125293. This part number includes the vents and the bracket in the back of the pod. If you wanted to buy the vents separate, the number would be 10037012.

 

If you could scan the pages, i'd appreciate it.

 

Instead of taking up huge amounts of space by hotlinking these pics, I'll just give you the links to my site.

The second picture is the parts list for the first picture. The illustration is usually just a vague representation of all of those setups. The 3.107 group list in the 3rd pic is a more detailed list. You can see both of the part numbers that I gave you....

Picture 1 - Illustration
Picture 2 - Part List
Picture 1 - Group List

I only had time to get the first one uploaded...I have to get to work. I'll upload the other 2 tonight.

-Josh

 

OK the pics are uploaded. They may look to small, if they do, hover your mouse over the pic and a box with arrows should appear in the lower right corner...just click that it it will make it 1500 pixels wide. If that doesnt work, just right click save as and then zoom in using another picture editing program.

-Josh

 

Anyone know where I could get the radio trim that plate for the radio pod that has the "Performance Sound" badge on there? I've seen so far it only came on '85 T/A's. Anyone know who has them?

Thanks!

 

The wife has an 85 T/A with "TRANS AM" mudflaps, she is missing one. Is this in your book?

 

Yup, this was a "Non-Production" option and those are in my book. You wouldnt believe what options can come with these cars!

Anyway, the # for the "GUARD PKG, FDR SPLASH (BLACK W/WHITE LOGO)(TRANS AM) - 997687

 

Hey Josh

Could you tell me the GM part number for the coil spring insulators, front and back? These would be the rubber insulators (or spacers as some ppl call 'em) that fit on the ends of the coil springs in the suspension..

For the record I have a '87 IROC 5.7L .... not sure if that matters but it might

TIA!

Stan

 

Front is 14047915
Rear is 10019587

They are all the same from 82-90 regardless of engine or RPO codes.

 

Yer the man Josh and doing the Thirdgen.org community a great service....

When I have to go into a GM dealer to get a part I always like having the part number because sometimes they don't know there head from there azz!! lol

Thanks

 

Hey...when I look for the part number on GM Parts Direct.com I can find a listing for the front insulators but not the rears...says the part number 10019587 is not found....

Oh well... one out of two ain't bad... least this will point them in the right direction! LOL

 

I had the same prob when I checked their site. However, I have that problem a lot of the times whenever I go there to look up a site. The best thing you can do is call a local GM parts dept. and ask them if it's been discontinued. If it isn't discontinued then you can contact GMPD and they should be able to get it for ya.

 

Hey Josh,

Can you get me the p/n for an 85 trans am headlight motor switch the one that goes inside the motor with a fuse inside inside it (I do not know what to call it) but it is in all 82-86 headlight motors)

Thanks

 

It didn't give me internal breakdowns for the headlight motor, but I did find a switch part number that I think is what you are looking for.

Here is exactly what it says:

SWITCH, W/BRUSH HDLP (1982-1986).....P/N=22038870

 

Thanks Josh, thats exactly what I needed

 

you deserve a metal for all the help!


What is the name and number for the door panels for my 87 formula. The panels are the same as a GTA. I think they are semi- rare. Could you scan the page that way I can see the part numbers for the trim pieces also? Mine are the ones w/o the pocket

Numbers for for 87 center console shifter boot, subwoofer gain switch and the black trim pieces that cover the front seat tracts.
