OP, the 4x4 case should be stronger if its a real K case, just need a 4x2 output shaft and tail housingi have a core comming out in a week or two. (700r4) its a 4wd version though.
it still works, it just lost reverse and were just slapping another used in it. may be an easy fix.
Ill ask my buddy what the cost is on it and let ya know if your interested.
