Dave, thanks for your suggestion. The point I am at with this kit I can remedy this problem, but am limited to what parts are in the box or I must create. With the front axle and wheel/tire mocked up I have this width issue. The correct width can be obtained without the brake hub, backing plate but that won't do. I do have room to section the axle, I suppose pinning it for support would work the best, then use what the kit supplied.
Another option I looked at was thinning the brake hub and enlarging the centering hole and making a super thin backing plate with non-rotating wheels. That would be acceptable but not preffered.
I have seen many builds of this kit here and most have an acceptable wheel spacing, just hoping to get some experienced thoughts to ease the pain. Thanks again.
