the hubs will have to be changed and driveline lengths may be an issue but i doubt it. other than that it'll be a direct swap as long as you get a divorced for a divorced and a married for a married. Hope this helps.
I believe the tailshaft adapters are differant as well but can't recall and the overall length of the transfer case is differant. I have seen several people ask about this but have never posted any after action reports. Let us know what you find.
