I think its a good option, in my neck of the country mopar parts are almost impossible to find. So that leaves you finding stuff online, either here or ebay. I have been looking for a rear end for my a body for some time and everybody wants $700 + for an 8 3/4 that doesn't have desirable gears, usually an open carrier and still has drum brakes plus the cost of freight. You already have the rear end so all you need to do buy a new short side axle ($100) and pay somebody to cut, shorten, and reweld the housing if you can't do it yourself ($100 - $200). That leaves you with a rear end that is relatively strong, has tons of parts support, has disc brakes, good gear ratios ( most 4 wheel drives are 3.55, 3.73, or 4.10) as well as a good possibility of being a limited slip. I'm no expert, but it seems like a good choice to me.
