I am looking for a 5" on 5.5" wheel hubs that will fit on a 1 or 1 1/4" axle. I know that older tractors have wheel hubs that are 5 bolt, (wheelhorse etc.) but I do not know if one is made with the specs listed above. Can someone help me? I am looking to build a monster mower, with an axle like a go kart, and I cannot find a wheel hub that I need.
