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 .
