Adam, HME (Hutton Motor Engineering) reproduced the gold dash appliques back in the early 80's and 90's. Previous to their reproductions the only option was to buy the entire plastic bezel from GM, and these have not been available since the early 80's. The first run of reproductions used the same materials and tooling as the original GM parts. The later runs used different tooling (hence the 2 piece design Jay talks about) but still used the original material type. I don't believe HME produced any inserts since the late 90's, so any remaining ones in the club inventory would be from HME's old stock.
