aren't 91-92 t/a tail lights exactly the same as 85-90 t/a lights. if so why does gts make different tail light covers which say they are specificly for 91-92.

 

Because the 91-92 style are the 2 piece-while the 85-90 style is the 3 piece style.

 

what do you mean by that i've seen 91-92 t/as and the taillights look exactly like the earlier models

 

They aren't, sorry I don't have a pic right now but they're def. 2 pieces where the more plentiful ones are 3 including the middle bird.

Believe me i didn't know the 91-92s existed until I saw a pic and started asking around just like you are

here is the 91-92 style, notice the obvious differences in the taillamps?
I personally like the 91-92 style more.

 

Good Luck finding a set, not really plentiful...

Actually they are very plentiful....they are just a little pricey. You can order 91-92 Trans Am tail lights from NextGen. I believe they are around $200 a side

 

Personally, I like the 85-90 style better.

I like the 91-92 style better myself.
They have that cleaner flowing look to them.

 

My 89 GTA with 91-92 GTA taillights

 

If i remember it right, only the 91-92 Trans ams and GTAs have the 2 piece lights. Firebirds and formulas got the regular base model 3-piece deals.

 

I prefer the 85-90 style myself i don't like the amber signals on the ends.

 

wow--this thread came back from the dead!

 

Here's what I had on there.

 

helpfull pic

 

1991-1992 GTA's and Trans Ams got those lights..

Also, since we're on this subject, the '82-'84 Trans Am lights were black and lit up red while the '82-'84 Firebird lights were red..

Another little taillight trivia note is that the '85 base model birds got the revised bumper and nose that carried on from '85-'92 but came with the old style '82-'84 lights...

 

I prefer the 82-84 style myself..

 

Wow, no kidding. I guess Dark Man C really wanted everyone to see his taillights.

OK, since we have the montage of taillights, how about the conversion chart for wiring harnesses? I put '86 TA taillights on my '83, and was able to use the stock harness. I understand Formula harnesses are different and you can't do that with them. I was also told the 91-92 T/A-GTA lights had their own harness. So who knows what swaps-to-what and what modifications need to be made?

 

I wanna jump in on the bandwagon.
