I have a twin of this that I use for parts, that will work on a 1988 LT-F250 2WD . Any thing that is unique to the 4WD may be available. ie choke cable, carb etc. I have the from brake master cylinder and handle complete front driveline, short of the rt ft inboard drive axle, I will keep the engine top half but the complete gear case and engine lower unit will become available. As I said though anything that ill work on my 2 wheel I plan on keeping.
Let me know if any of this is feasible for you.
Hope it works out for you.
Tim.
