The motor will bolt right in. Id look for a 93-94 motor or a newer one that has been converted to mechanical fuel injection. The only problem I foresee is the turbo may get in the way of some things, especially if you have AC. Also get anything like glow plug controllers etc. from the donor truck. Are you planning on using the NV4500 and the tcase out of a newer truck or your present tcase. If you plan on the later, Advance Adapters has all sorts of adapters to mate up whatever you want. If you use the donor tcase you will have to get a front diff with a driver side differential. Im sure there are some things I missed but you get the basic idea of what is needed.
