This is what I can tell you,71 seats you better have good foam.The 71 has something different in the frame itself.My 71 RR came with seats like the above pic,(original bench car)Everyone I asked either didn't know or said I needed 71 seats.I couldn't find 71 seats that where reasonably priced so I almost gave up.Found a guy that had several rr's said don't worry put 71 covers on my later seats HE WAS CORRECT fit perfect!My listings fit perfect, the only difference that you can tell the year is incorrect on my car is because the backrest button is in the plastic arm and not in metal as the later back is one piece.
