85 CJ-7 engine conversion

I have an 85 CJ-7 and want to swap the engine. I was thinking of
buying a late 80's or early 90's chev 1/2 ton 4X4 with a V-8 in good
running condition and rusted out body and basically stripping
everything away as to make sure I still have an engine and trans that
still runs with wiring, computer etc.. all still connected. All I need
to buy would be a Dana 300 transfer case adapter and V-8 engine
mounts. Are there any particular years to look for in a donor vehicle?
