I have to replace arm rest pad on my 1980 dev.coupe,is the arm rest the same size in both sedan and coupe. I seen a picture of one in a sedan and it takes up full length of door,in coupe it only takes up 3/4 of door,so I think their the same size,I would have more to choose from if they were the same size,also would fleetwood be the same. tnx Creeker
