precision plating, 2611 locust st., quincy ill. 62301, 217-223-6590. I've had them do several high end jobs for customer cars in the past. I felt they were reasonable and fair priced. The work they did for me was very good.
Farther away but The Chrome Shop In Menasha Wisconsin does outstanding work. Not cheap. Dave/Green Bay
