that would've been the easiest way to make up for the exact difference in pinion length between the D44 and D60. I've already dropped the shaft off and told em to whack 2.5" off of the front based upon the wear patten that was visible on the slip joint from the seal, I could see where it was when the truck was new, then as the springs aged and sagged it compressed. Now with new springs and new front axle, 2.5" puts it back where it was in the beginning.
