To answer Mike's earlier question: Stockton wheels in Stockton CA will take your original wheels, cut out the inner, and rebuild the wheel to whatever specs you want. This will allow you to make the switch to radial tires and keep using your original caps without any modifications. They quoted me $110 per wheel and will powdercoat them or paint them at an additional cost. I'm tickled pink about this and am still trying to learn what sizes would be best for my truck. I'll be sending them my wheels as soon as I'm comfy with my decision about size.
