70 bench dodge plymouth difference

[brian70bee]

Hi all,
I've got an opportunity to buy a 70 Plymouth bench seat to replace the missing bench seat in my 70 coronet. I know the 70 Dodge bench seats are unique for that year and that I will have to replace the seat covers. Wondering if there are any differences in the basic seat frames and rails between the two - does anybody know? Thanks.

Best I know of, there is no difference in the seats themselves, just the covers. Over the years I've heard that the Dodge seats had more padding in them than the Plymouth's. BUT, I've never seen anything in print to say that is true.
