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.

also wondering if a 2dr seat with rear speaker would fit in a 4dr H/T

I don't have my 4drht here but going off memory, the seat is wider because there are no side arm rests and filler panels. The seat bottom is also more rounded on the corners.

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.

Forgot to finish my thought. I will be driving to Florida in January, we can meet up then.
