minor update-
think i found the correct axle tube.
this came as a complete assembly, drum to drum, with a chewed third.
it is different from a 2wd rear - wider, larger brakes, w/ spring perches on top.
mabe some of this differential is useful....(?)

'94 "tracker", with some parts from suzi the psychic.
other modifications made, with more to come.
some intentional.
suzitoo should get me fishing.
