i thought about doing this same thing, i was gonna get the truck and swap all of my stuff off of my 82 (tranny & t-case, axle's). I was told by a couple of poeple it would not work i would have to get a taco tranny and t-case, not sure how that would work either is what they told me. Hopfully this will help a little. They told me i would be better off just buying a 4wd taco and sas it, less heart ach's and trouble.
