I am restoring a 62 Series 2..... I am ready to remove the Rear end and I was planning to separate it from the leaf springs.... I removed the U-Bolts and bottom plate.. There is a pin that connects the bracket on the diff. Housing to the springs. It has a 7/16 nut on the bottom and a bushing of some sort that sits directly above it. The other end is a flared end. Of course when I try a d loosen the bottom nut the whole Assy just spins....any suggestions how to remove this. I realize I can leave he springs attached to the differential, but I was hoping to separate all of it to clean and polish before before reassembly... As always.. Your suggestions are welcome....
