SD tail panel trim. Quite hard to get. There's a guy that makes reproduction billet pieces in Ontario, somebody on here will direct you in the right direction as I don't have that info. Hope you find what you need.
There is a fellow here in Kelowna who has made 4 or 5 sets for guys here on the forum. Last one was at least a year ago. Can't remember who it was but I can check my messages as they told me after they received it. I can look up his number here later if someone doesn't pipe up. Steve Roth is his name.
