attn; fastback experts, seat question

It was Legendary that told me I could not use '67 covers on a '68 rear seat.
But no definitive answer as to why. I just have a hard time believing that chrysler would change something like that . It would be an expense for no
aparent reason.

Has any of you used a '67 rear fold down in a '68, or visa versa? did it bolt in?

IMO the 67 stuff has a classy finished look to it .
