I see well then I'll probably go with a beefed up w56 since it wouldn't take as many donor trucks to perform the build from what I've read. Also, have been looking into building a full floating conversion for the rear end of my truck(front range offroad kit), I like the idea of it being less stress on the axle itself from what I've researched and safer if one snaps. I've seen trucks with this conversion with aisin manual locking hubs on the rear. My NEW questions being, do they actually function the same as the ones on the front how so? Also, could I put a 4.88 spartan locker in with that set up? How reliable would it be?
