Theres no adaptor involved, that how the dayton wheel works. Ussally has 5 or 6 larger bolts holding it to the hub and brakes drum. Most of the time you see daytons, the truck has air brakes, but not always. The ten bolt wheel, as most here call it is a budd. Unless you have a truck made before the 30's this is the only 2 choices there are. New truck still use the dayton pretty much like the older ones. The budd comes in many differnt hole patterns and circle sizes. If you want to put the dayton style on your truck you have to have all the parts not just the outer one you see. It would be a differnt hub, drum and the cast spoke part. Look for a semi-trailer of the same vintage as your truck, chances are it has the daytons your looking for.
