The F (Volare, Aspen), J (Mirada?) and M (LeBaron, 5th Ave) bodies all came with disc brakes, only. The spindle is slightly taller than the B/E piece. I always search for 1985 Dodge Diplomats just because so many of them were cop cars with P/S coolers, etc.
All FJM cars used the 10.875" rotor but the large adapter for the 11.75" rotor bolts right on.
Using these spindles seems to be gaining popularity daily. They have minor suspension angle disadvantage at initial launch for drag cars, but seem to offer certain camber advantages on street cars.
Oops, Asheboro not Asheville.
