Firewheel Classics is the place to shop for first gen Camaro parts and accessories.  They also carry Chevelle, Nova Firebird and TriFive Chevy parts.  They have some of the best prices in the nation, the most knowledgable staff, ship nationwide and even to other countries.  These folks really know their stuff.....they don't just sell classic car parts, they actually own more than one....here's a video from a customer appreciation held at their store.
