Hey folks, I am currently building my 1974 f350 dually and it is approaching time to tackle my wheel and tire situation, what I want to do is eliminate the duals and run a wide 16 or 18 inch mag. Either that or do a 10 lug conversion so I can run Alcoa 22.5's. However I have coin wheels and I was wondering if the hubs have the indents for the coins and if so do I have to get new hubs or something to convert it? Any advice or help would be greatly appreciated.
