1981 diplomat coupe

[Pete]

Does anybody know if Fifth Ave or Diplomat 4 door rear seats will fit in an 81 Diplomat coupe (2 dr ) ? I found an 87 Fifth ave 2 AHB Diplomats and an 89 Gran Fury in a pick n pull yard in Detroit . my buddy pointed out that the rear seat cushion is squared in a coupe and rounded in 4 door cars for easy entry into rear seat /door panel clearance. He doesnt think the rears will fit. I just wondered if anybody tried it .

I think the shape of the seats is different between the 2 door and the 4 door.

The lower cushion is definatly different . the rounded edges wouldn't bother me . i just would like to know if the overall width is the same . i know the mirada seats are wider by about 4"
