Actually The diffs may be OK...As far as a money pit I gave a used battery charger for it...It needs a battery box a linkage kit and an engine I have a couple mills in mind.I'm guessing not so big on the engine with the old style diffs?And can I just drop the newer diffs in the older cases ?...It's really in pretty good shape just oily and dirty.Is a .32 going to be too much on the old style diffs?
