Hello I have a 72 dart swinger with a 360 and 727 it has a 7 1/4 rear diff and my ex father in law just gave me a Ford 8" diff out of an old falcon, I know I will have to fab some stuff like relocating the spring pads and possibly the drive shaft. So I was wondering if anyone had any input on this? The 8" diff is 4 inches shorter over all and the spring pads will have to be moved out 2" on each side.
