Bill, as Jac Mac has already said, the caliper sits outside the wheel flange by a significant amount, and the fear is that it will foul the inside of the wheel.
What you need to do is;

1 determine the position the caliper must be in to leave say 5mm+ clearance from the inside face of the wheel. This then determines the position of the rotor to sit centrally in the caliper. If the rotor will foul the hub or lugs in this position, you are in a bit more trouble. Also make sure the caliper fits within the wheel inside radius.

2 from this rotor position and the hub flange dimensions, determine the bell required to mount the rotor.

3 all being well you can then design the caliper mounting bracket. If you are lucky it could just be a piece of flat plate. I suggest you could do some hand sketches to explore the possibilities.

It may help to see my threads which contain some pictures and section drawings. Do an advanced search on my username for threads started by me and look for threads on the front, and especially the rear brakes you will see some pictures of mine and others brackets.
