Yenko "mylar" chrome sticker

[yenko charlie]

Does anyone know if there was ever a chrome finished Yenko "bars and stars" mylar sticker used anywhere on any of the cars? No color, just a black emblem with a black border on a chrome background. I have a few that I bought many, many years ago from someone who worked for the dealership (can't remember his name). They may have been used as a sticker for the air cleaner, valve covers, trunk decklid, (????). I have 2 different sizes (2 1/4 x 7 and 2 1/4 x 5). If I can figure out how to post photos, I'd be glad to post them here. Drop me a PM (Yenko Charlie), or post an answer here.... Would like to get rid of some before I reach room temperature!! Cheers, Charlie
