I have been looking for these wheels also. A friend of mine has a 66 C60 dump bed that has the 10 hole 8.25 paturn wheels that are the widowmakers. He already baught 2 new 22.5 wheels from accuride because the front two were flat. Now we can atleast roll the truck oround easier but we want to replace the rear before we get the truck running and start driving on the road. The only vehicle I have even seen with the 22.5 inch wheels with this bolt patern is a mid 80s chevy school buss. Has anybody ever tried to build a set of these wheels by using the center out of the old wheels and welding them in some bud wheels?
