There was a guy who was a member here for a while, user name wheelkid, he hasn't been around here for a while, but I see he is still posting on HAMB. You might PM him on there and ask him the question. His Pop owned one of the major wheel companies at one time, and they still are involved to some degree, and he seemed to know his stuff when on here. Maybe he has the indexing machine and some simple UPS shipping might net you a drilled and possibly rewelded rim.

If he doesn't pan out, call some other wheel companies, and see if one of them will help you out. Most of these guys are rodders and will understand what you are trying to do.

Sorry to send you searching on brand X, but it is the only way I know for you to contact wheelkid.
