The steering column should work just fine. You should modify it just like installing a van tilt - collapse the intermediate column, move the NS/reverse switch, install the 2 rubber grometts and mounting ring, and if needed use the turn signal wiring adapter. Depending on the year of the van it may a fiber optic to light the PRNDLL or if newer the light bulb. The radio if original to the van should interchange. I don't know what year they changed but early vans have the same defrost vents in the dash.

8-lug rotors,calipers, spindles will work with disc brake front ends.

The wiring harness may work. Due to the body style differences the routing (and therefore the length) may cause problems.

The door parts do not interchange.

Have fun - Bob
