I used to be in the wood boat restoration bussiness and we did alot of business with Jennings Plating. They were in a bad part of warren as we were only there about a ten minutes and our hub-caps were stolen off our company van. I think they had a contract with some company that supplied new GM emblems for the muscle cars. Last time I was there they had boxe's full of Chevelle door panel emblems (SS)

They even did President Clinton's Cadillac grill as it was damaged by flying debris from a jet engine. (thats the story they gave us??)

They did my 69 Superbee hood scoop trims and they turned out mint along with a really pitted BERGER Chervolet emblem. It too turned out perfect.

Those guys knew what they were doing! BUT, With the new law's and such maybe they had to shut there doors, its been a few years since I talked to them.

Good Luck.
