Need a place that can widen a set of 1-piece aluminum wheels, preferably in San Diego but anywhere reasonably close will do.
Weldcraft is a good place, but not exactly local.
Eric Vaugn is a master at widening, narrowing and repairing aluminum wheels and doesn't charge an arm and a leg. I lost his address, but did a quick search and I think this is the one I used before:
