I am in the process of putting a 56" wide Dana in my Aspen with the springs in the stock location. It is TIGHT. I believe the stock A-Body length is 57"?? I will work just fine I think if mine fit. I am using 15 x 10" rear wheels with 3.5" back space.
The current tire is a 9 x 29.5" The rear is lowered about 3" from stock ride hieght.
