The 82 dt engine will have the rear suspension oil pump on the head. Someone else will have to speak up if you can somehow disable the pump. Some of the vacuum fittings on the throttle linkage may be different but you can switch that over from the '84. Pull the engine and trans as one unit. It WILL save you alot of hassle.
