64-67 A-Body Rear Seat Fitment

[marxjunk]

depends..a cutlass and a 442 would have a narrow seat..a f85 would be the wide seat..its about trim level..not sure on cutlass post cars

theres 2 seats...approx 54 and 60 inches wide..

buick specials and GS post cars have the wide seat
GS hardtops have the narrow seat

gtos have the wide seat

chevelles have the wide seat i believe...cant remember right now

easy way to tell which seat ya need is look at the arm rests..if they bolt to the back door panel area it uses the wide seat..if the car has the large armrest that looks like a convertible armrest basically..it needs the narrow seat
