Hello all. I have a '53 3100. I lowered it about 4" and converted it to 4 wheel disc brakes with a 5 on 4 3/4" bolt pattern (speedway front disc brake kit) I am now looking for wheels. The 6 bolt wheels that came on it are 15" diameter, 5" wide and about 3 1/2" backspacing, depending on how it's measured. I'm wondering if those could have been the original wheels? Or would originals have been 16" rims? What are the dimensions of the original rims? I'm also looking for input on what wheel dimensions would fit without any clearance issues. On the rear I moved the shocks inboard of the frame rails and tubbed the box out 4", so I gained a couple inches of clearance on the inside, with the frame being the limiting factor now. I would like the rear wheels a couple inches wider than the front wheels.
