I just bought a '75 KW day cab with 290 cummins and the truck is in excellent condition. It has aluminum fronts on it that look good, but the rears are the Dayton 5 spoke style wheels. I don't like the Dayton style that much, just painted black. How hard is it to change them over to a center style pilot hole, so I can find some rims to match the fronts? If its to much trouble to change what are some alternatives?
