Just to add my take on this, I ordered the rebuild kit from Jim Carter and it came with an instruction manual. I read through the instructions and thought that maybe it was more than I cared to take on, but I've got a buddy that has done a couple of rebuilds and told me he'd bail me out if I had trouble. Turned out to be much easier than I thought, no problems. The only gripe I had was the manual that came with kit had nothing about the bushing replacement but my shop manual filled in the gaps. The toughest part for me was like all things on a 55+ year old truck, getting the bolts loose to remove the gearbox.
