What is wrong with it? From the research I have done, I am keeping mine, swapping shafts and welding the housing.
Is yours shot, grenaded, bent, pretzled, snapped, or just undesireable?
If it is beyond repair, look for a Dana 44 IMHO. I understand Scout axles can be made to fit. Do a few searches, there have been some good discussions on this in here recently. (look for M20 or AMC model 20.)
