My camaro has some charcoal grey seats that i think are 4th gen seats. The drivers side has 2 levers in the front left and right. One slides the seat back and forth and the other tilts the whole seat top and bottom back. Ive never seen anything like that. Here are a couple of pics.

 

those are stock firebird seats.... i had them in my 91

one is to move back and forth and the other is to tilt the seat front/back

 

So there 3rd gen seats. Thanks i didnt know what they were just knew they were not camaro seats.

 

I've got those in my T/A and it's broken.

 

I had that style seat adjuster, was option AH3, IIRC

Sold it when I bought a power seat track, it's actually a pretty handy seat track.

 

My leather seats in my 1989 GTA has them

 

What's really exciting is when you get three levers in the front. Sometimes I get all giddy and can't decide which one to pull.

 

I agree, I took those seats off my 87 T/A and I have 4th Gen Camaro seats and both have those two levers...

 

my car has them. Got the seats from an 89 GTA

 

the full articulating seats have 3.
