The best source for finding chrome exterior trim parts and components is EBay. Auto wholesalers, junkyards, auto restoration businesses and body shops appear to prefer it to listing parts on their own websites. The parts still may be very difficult to locate.
An alternative to purchasing used parts is to restore the original chrome parts already on the vehicle. The process is delicate and requires special tools for removal, but it is the least expensive option. The best special tools are made of plastic. The chrome parts need to be removed, restored or dipped, and reattached. They are fragile, easily damaged and require a gentle touch.
