i believe the 65 has the nut. so 66-7 is best years? yes I have bbp rims to use. how much wider is the 66-7 b body rear vs the a body 8 3/4??? thanks for the info..
Spring perches would need to be moved in 1/2 inch on each side to fit into the A body. Many people will tell you to just pull the springs out and bolt it in. That WILL work, but I always ask, "why didn't Ma Mopar do it that way?" I don't think it's a good idea because it would put undue stress on the front and rear bushings, bolts etc.
