Cawley I never did receive the information fro Show Cars. But today I crawled under the Barracuda to look for any tags on the parts. They were there. I found stickers that were labeled STINGER FIBERGLASS. So although I ordered through ShowCars, someone else did make my parts. I went online and found that Stinger Fiberglass is now affiliated with AAR Fiberglass. That would explain why mine fit so well. Their description in the catalog even says that the '69 side marker indentation is there as mine were.
