4x4 swap

Hey all...I recently purchased a 95' xj 2 door 2 wheel drive sport. I have found another xj not sure on year but the motor is burnt. I can get this for $500 and it is 4 door 4 wheel drive. Everything under hood is burnt but everything else is good. What problems if any will there be to making the 4x4 swap. Should it bolt right up without fabricating anything. Would it be worth doing for this price or at all. Thanks for listening hope to here back from someone!

Yes it all bolts up.
It should be a breeze with a complete donor vehicle.
a few caveats exist.
there were some transfer case differences.
around 1990 the transmission / transfercase spline count changed from 21 to 23.

If your donor vehicle is 91 or newer it's really a remove and replace operation.
TLMAN and many others have done it do a search.
