If they are some wheels that you absolutely must use you can either advertise for a wheel like it, check out some places that sell wheels and maybe just maybe they have one that was a display. Call a few wrecking yards around and see what you can come up with. Check swap meets. Post a pic on here and maybe someone can help you out. And worse come to worse if it goes on the front maybe the rotor can be drilled for the bastard pattern. The only thing that would do though is put a stop to tire rotation. Personally from all the options I'd either redrill or post a pic and see if some of us members can help you out.
