2nd gen convert to diesel?

[recian]

So in response to the turbo diesel I mentioned before the guy dropped the price to $500. It's an 84. The body is in rough shape. It needs a head gasket since it overheated. It's a turbo diesel 4wd 5-speed. Would this drivetrain fit in my 94? I know I need to change the front end for the front diff 4wd but would the rest interchange? At this point I'd have a doner truck. It is a short bed so the driveshaft may fit. The engine should be a 4D55 TD which should be the same as the 4D56 that came in the 2nd gens. So if I get mounts it should work. We've been doing some research but idk what to do about 4wd. May look into doing a 2wd since my truck is 2wd. Could I change the existing trans' tailshaft to a 2wd?
