I have a 90 vert and want to put new seats in. I have found some in the classified ads, but im unsure if they will fit. Did the coupes have the same dimension seats as the vert. In other words, will the rear seats fit under the plastic of the tanneau(sp?)

 

The F-body coupe and convertible rear seats are the same. Just make sure that if yours has a split-rear seat back that you are buying a rear seat with the same split rear back. You can swap a non-split rear seat back in place of a split rear seat back, but that involves modifying your car by cutting off the inner hinge posts from the driveshaft tunnel.

The only rear thirdgen seat that may have a problem in your convertible would be those from a 1988 Firebird GTA notchback or 1989 Turbo-Trans Am (due to the headrest). But due to the rarity of both of those models, you'll likely not find those rear seats anyway (and would pay through the nose if you did).

Thanks for the info, you saved me.
