I think some of the truck/van stuff is different a little different but I don't know which years. It might work. It might not. It depends if it has that later Chrysler column that came out in the late 80s on some vehicles
The answer to the question is yes a 1989 Ram Charger steering wheel will fit an M body steering column perfectly, at least an '84 M column with tilt (and yes I know I need to clean the wheel!)
