I'm pretty sure that you can use the Ford housing with Wagoneer knuckles and spindle, then use the Ford rotors and hub.
I know that you can use Chevy knuckles with a Scout 44, so I'm thinking that you can interchange most of the parts. You will have to match the spindle with the knuckle and the rotor and hub with the wheel.
What about the caliper bracket and caliper? You will have to compare the two and see how if the diameter of the rotor will affect the bracket. I think it will work. Should be an 11" rotor.
