ive done 2 of these swaps, great swap, the 2wd frame is actually better hen the 4wd in the respect that it has more of an arch in the front to accomodate steering, shocks-travel
i even used the 2wd steering box for a few years, with 40s and i competed in ameture rockcrawling comps...i eventually upgraded to a 4wd box, but only cause i found one super cheap-lemme know how else i can help
