Thanks for the input. Here is where I am at with mine. The caliper clears the king pin and the plan right now is two L shaped brackets off the top of the spindle to the disc brake bracket itself. I am mocking those out of plywood this weekend to make sure it works before I machine them out of metal. I will post more pics once I have the brackets mocked up. For the bearings, I bought roller bearings from Chev's of the 40's.
