I was under my 92 GTA 350 the other day looking for the code on the rear end. I found what I believe is the code on the front of the passenger side of the axleshaft. Is this where the numbers are located?
These are the numbers I pulled:
SPM C 154 2 (P could be F)
These don't match what I have for numbers in my book. Can somebody help me identify what I have?

Do you still have the original SPI lable in the rear locking compartment? The RPO code for your rear should be there. I'd think your car being the 350 would have G92 and maybe either GT4 (3.73) or GU5 (3.23).....

Nice to see another 1992 GTA on the board! There are only about 4 or so of us on the board including Dirk the Admin. but they don't post much.

Here we go again...

In 91-92 (probably 1990 also) every L98 Firebird came with the R6P performance package (similar to G92, although the late firebirds don't use the G92 rpo code from what I've seen). The R6P package included dual cats, posi, 3:23 gears, etc. If anyone has the RPO G92 on a 91-92 Firebird please let me know. There were no options to the buyer of a late L98 fbody concerning gears. THEY ALL HAD 3:23's.

I still can't help but think that the admin of "THE 3rdgen Firebird Site!" should know this stuff.


Back to the original question. The codes should be where you found them, but they're so seldomly used that finding a correct guide to the codes could be a PITA. What book are you using to decode them? Unless its a GM shop manual for a 92 Firebird chances are it won't have accurate info. On my cars I've never been able to find the codes on the axle tubes.

SPM C 154 2 (P could be F)

The closest code I could find is 2PM G 154 2:

2PM: 3.23 ratio limited slip
G: Chevrolet Gear and Axle Plant
154: 154th day of the year
2: Night shift

:hail: :hail: :hail: Sorry it slipped my mind that it was the 3.23's while I was responding. I guess sometimes I just don't have the awesome memory that you do Drew.

I love my 92 GTA.
I wasn't aware that they only came with 3.23 and posi. Thanks for the heads up.
I did find GU5 on the label. I was using my crappy Haynes manual and it only had axle shaft numbers.

92GTA - where'd you find 508 for the prod numbers? I read somewhere it was more like 270 in north america.

thanks all

It was thought that the number was 226 but I just found out a week ago it's 508. A member on my board sent me the VIN numbers for ALL 1992 Firebirds and doing the math there were 508 American GTA's made in 1992, not 226. I've already emailed Frankie of the GTAsourcePage and informed him. In addition to the 508 U.S. GTA's there are 48 Canadian GTA's and only 2 known Euro made GTA's, suppossedly GTA's were not available for export to europe in 1992 but Frankie and I have managed to find 2, a black one that is currently owned by a guy in Germany named Alex, and blue one that was destroyed in a wreck a few years ago. So the total known world wide 1992 GTA production is currently at "558". The only way this number will change is if more euro GTA's are discovered. I'm also going to 100% verify all of the 508 92 GTA VIN's numbers I have to make sure that they are all real GTA's with Y84, I think I'm going to need a friend that works at a dealership for that one It could turn out to be 507 or 509, so for right now the number is "508", exactly the number that Pontiac Historical Services claims.

My opinion:

If you advertise yourself as an authority you should make it clear when you don't really know what you're talking about and when you're taking an educated guess. For someone that claims to be THE as in THE ONE AND ONLY or THE BEST source for thirdgen Firebird information, you should be aware of a fact that many other people know. Given your own horn blowing a simple mistake isn't excusable.

G92 isn't mentioned anywhere in any of the 1991 Firebird documentation I have in my collection. R6P IS listed in every piece I have, and its noted that R6P is REQUIRED equipment with the L98, and is optional on the LB9. It blows my mind that you're so concerned with production numbers (which are insignificant BTW) yet you don't know something as simple as which gears were available. I mean in 91-92 there were 2.73's, 3.08's, 3.23's, and 3.42's. Not too hard to remember. You might want to write this down.

LH0 auto 3.23
LH0 manual 3.42
L03 auto : 2.73
L03 manual : 3.08
LB9 auto : 2.73
LB9 manual : 3.42
L98 all : 3.23

FWIW some of my documentation shows the T/A LB9 auto with 3:08's and it shows that the LB9 auto wasn't available in the GTA. I'm not going to research it any further, it might or might not be accurate but in general the above chart is accurate.

Its easy to remember, just keep in mind that the 5 spds have better gearing due to the disadvantage of the T5 transmissions gearing. The differential gearing takes up the slack. Likewise the V6's have better gearing to make up for the lack of hp/tq.

Once again the only reason I'm giving you grief is your claims of superiority. If you don't know your facts then quit telling people you do.

Dude, all I'm saying is chill out. I can't remember every single little thing that's why I have it either written down of on my site. I do have a life outside 3rd gen's. I know all of what you just said it just happens to be that I'm at work so I have to go on my memory. BTW, I NEVER said that I know everything there is to know about 3rd gen 'birds and as you can tell my site is a work in progress that has just fraction of all the info that there is out there. I update it all the time but's hard to get it all done when I work 75 hours a week and have a family and my car, the site comes last, not first.

My Opinion:

There's not ONE person in this entire world that knows EVERYTHING there is to know about a firebird/camaro. One person may say this is what info I have ... and then another person will come right behind that person and say this is what I found and then another will do the same thing and all 3 pieces of data will be completely different.

Also, some people find it easier than others to remember certain particulars of a car and I find it completely contradictory for another person ( especially from a moderator :nono: ) to come up and flame someone for letting something "slip their mind".

I've been guilty of the same thing myself on this board and remanded for it so personally I feel we should all leave the arguements, personal attacks, and double standards off the board and help out the people that actually NEED the help.

My job here as a moderator is to make sure that everything rolls smoothly and that the information is accurate. A large portion of the membership here consists of people that are trying to learn about their cars. When they come in and see someone that administrates "THE 3rdgen Firebird site" they may very well expect the information coming from that individual to be accurate. When this person posts something incorrect then people who read it will be confused. I'm trying to prevent that by providing the correct information and doing my best to let the person in error know what was wrong, in an attempt to prevent it from happening again. Its not a flame, its taking something incorrect and correcting it.

86TpiTransAm

Correcting is one thing and flaming is another.

I agree on your job description and agree that you should correct misinformation but I think the way you "worded" your post was seen as a flame, not only by the person you were directing it at but also by me and probably by others that didn't speak up.

Again, I was only stating my opinion. Let's just leave it at that.
