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

If the driveshaft looks shorter (more compressed) than it was, the new springs actually lowered the truck. Or... maybe you have 73+ front springs which would be longer hitting the spring stop and the centering pin would be further back. There is no worries about length on drive shaft with stock spec 72 springs. If axle is in the same place as original it will bottom out the same and shaft will compress enough. I can measure the stock front springs off of my 72 for you if you do not have originals to compare. Check overall length and eyes to center pin.
