Good morning everyone; I am currently rebuilding my 1972 jimmy, question is after I installed new front leaf springs,the front drive shaft distance suddenly got shorter,making the drive shaft too long? I also noticed that the left side spring shackle is up against the safety block on the frame. Is this right,or is another problem creating this situation,when the jimmy is down on it's weight on the ground? Thanks for looking, Tomq
