the front spring hanger is Ford F250 hangers welded to a receiver hitch cut to yota spring width, the front springs are yota 2wd rears, i am going to shorten the overload retainer to limit the pinion tip at full spring extension, the rear diff was bolt in just have to plumb the rear brake hose, then devise a park brake cable. Hmm maybe so kinda t/case mounted unit?? any ideas?
