B-Body Back Seat Interchange
I have scoured the interwebs looking for interchange info for full size back seats. I am interested in fit for the frames and not so much upholstery patterns.
Specifically, what back seats from other GM B-Body cars will fit into a '65 2-dr hardtop? I think (dangerous, I know) the '65/'66 of each model/style are the same. So, which are different / same: 2dr hdtp, 2dr sedan, convertible, 4dr hdtp/sedan? Do all like model/style bottoms interchange? It looks like backs are different depending on width by model and speaker/no speaker and then there is the folding arm rest on the GP / Bonneville. Some sources say the seats frames are interchangeable up to '70, some say '68, others say just '65/'66, and then of course google AI tells you something different every time you ask. I believe like year and style (2/4dr, couple/sedan) from other B-body cars also interchange. What is the truth? I just want to know what my options are if I replace the busted back seat bottom frame in the 2+2. Someone about an hour south of me had a couple of '68 seats for reasonable price that I can go pick up and not have to ship. -thanks

I believe you will find that the convertible rear seats are narrower than the 2 and 4 door. I know that doesnt help much, but its maybe a start.

If you can wait until January, I have a complete back seat for a 66 Bonneville 2dr hardtop in my basement. It is taking up space and I would like to get rid of it.
