Ok So I had a 90 jimmy w/ 63's rear and 57's front but now he is gone. Now I have a 79 shortbox. Will 63's fit w/o moving the foward mount foward. I am going to use a set of ORD shackle flips (switched sides to move the spring mount point back) and a set of Alcan 63" 4" lift springs. I plan on doing the measurements today but I was just wondering if any one had done it?
