Yup, I know about the differential thing. I do plan to weld the rear and detroit the front. Today sucks, I just saw that USA6x6 has a recently released 1 ton kit that is VERY affordable priced. The 2 and 2.5 ton kits, and the one I'd been working on were, are, and would end up being twice the other kits cost. I think I'll cut my losses here, which would actually even out had I bought a big kit and move to other aspects of the project.
