How have you other 1970 Mach 1 owners dealt with restoring the gold cadmium (or zinc dichromate) plating on the metal sport lamp housings? Most of the used lamps I've seen, including the ones I have, are rusty and slightly pitted. There are other sources for the housings, such as Cougars and Mavericks, but the wiring is different and I can't see a way to remove and replace the wiring without damaging the housing in the process. I'd consider buying a nice used set and replating them if there's a way to deal with the wiring.
I've tried playing with Eastwood's gold cad paint system. It just doesn't look right to me when viewed up close.
I've also tried my usual parts contacts to see if anyone has a pair of new lamps. No luck so far.
