An NCRS guy does an unbelievable job on trim rings. His name is Rick, goes by georickparts on eBay. Had my original rings from my 67 RS/SS done by him. Amazing! Took out some curb rash, a few dings. He can even remove the inner ring with the four clips on it and blast it and put them all back like NOS. I have his number, let me see if I can dig it up.
