Drum brake wheels, almost always DON'T fit disk brakes.
I used Master Power Brakes for my kit, it went right on and I am happy with the performance and cost. Its been 10 years now with out a problem.
Look at what parts are used how easy it will be to get replacement. If they are standard replacements, then go for the kit you like best. Custom replacement parts will be harder to get down the road, so that should be considered in.
Mine uses all Chevrolet calipers and rotors with one Ford bearing. Nothing I can't get at the local parts house.
