I picked up an extra set of 15x7 honeycomb wheels for my BFG radials. (from earlier posts you know I will be using the Polyglas GT's for show). Found these on ebay reasonably cheap and only about 25 miles away.
The problem with these wheels is that the internal steel supporting cone that runs from the mounting flange of the wheel to the center cap mounting point is usually mangled from years of abuse from tire machines, pried off center caps, really high curbs, etc. The normally pentagon shaped flange is commonly trapazoidal from the years of bad treatment. There is no way to access and repair the cone if it is damaged...unless you get creative.
Here is the set:
Here is the center cap area. Notice the ovaled out center holes:
