It came on the first 68 models. It's a really rare piece. I had one on my 68 GTS 383 Dart back in high school. I thought it only came on BB cars til I saw one on a 340 GTS. I wish I could justify it. Good luck with the sale. Someone hurry and buy it, because if it's here Monday.....hmmmm 500 firm? Any picks of the back?
