I've seen the tace bell commercial and from the quick glimpse I saw, I think it's a 68. I don't remember seeing the wing windows for the 67.

I was just at the yearly car show out my way. It's called Das Aucfest. It's supposed to be more of the way of really old cars that are mainly stock shape. They also have your typical camaro's, chevelles, gto's, mustangs. Most are all stock with the expetion of people adding new intakes and carbs. I did see 4 firebirds!!!!! 1 was a 68 that I took a picture of and 3 were 69's. There was a lot of course of the 68 and 69 camaros. So guy had a 67 camaro RS convertibe that he was selling for 24,000.
