Yes, I am sure I could have some machined, and I believe my lathe is actually big enough I could do it my self.
But I don't need any that bad, it would cost a fortune either to have them made, or just the time if I made them.
I think that hub piloted Budd type wheels are the best. But I find the adapters interesting, that's why I would want a set at the right price.
