This was in 64 to 67 group on face book. Don't know if it's still available. https://www.facebook.com/photo/?fbid=2898187140475548&set=pcb.795844161540476
I'd try all the known re-chromers. How many are left? There is one in El Paso. El Paso Electroplating. They are slammed from what I've heard. Six month backlog. Tri-city? Even Bumper Boyz. They might? have Cores. Who's that Buick specialist in Phoenix? Speedway?
The chrome platers have them, but they are very costly. I'm looking for a good used one, not a rechromed one.
