Thanks for the input, folks. I've been mulling it over for a couple of days now and I'm pretty well set on getting a whole replacement rear end. Good to know about the axle disparity though, splashoil. My main concern now is just being certain that the whole rear end I find as a replacement is a direct replacement. Any 64-72 1/2 ton is coil spring and should fit right up where the old one did right? I've heard that the 70-72's were a little wider, so I've narrowed the search to a 64-69 for the time being.
