Can I swap the rear housing from a 4wd nissan transmission to a 2wd. I searched around but couldn't find a clear answer. I am looking at a truck that is in great shape and low miles but 4th gear is gone. 4wd trannys behind ka24 are kinda rare, not to mention junk yard around here are dying, so I want to see how hard it would be to just swap the rear half of the housing over. Would the output shaft need swapped too?
