Have a 1968 chevy C-10 pick up. When I bought truck it had 15" deep rally wheels on it. The issue is this. The center hole in the rims are 4.250 but the round part of the hub is only 3.5. So the weight of truck is not on hubs but on the studs. So I need some sort of adater or spacer to fill in the emty space so the weight will be on hub. I,ve call auto parts places. But with no luck. I,m sure these items are out there but people at these auto stores don,t know where. Next week I can make me some spacers at work. But would rather buy some if I can. When I explain this issue to the auto parts places. They don,t know what I,m talking about. Thanks, John
