Just so you know, 65 and 66 are different. The stud in the front is in a different place and they have a slightly different curve where they sit on the fender. The little Gt fins are the same though.
Holy cow. I really wish I had the money to pick these up. Even though I don't even have a 65 dart right now, I will get another someday and know it will need these. Lol
When I was really little, my parrents had a 66 valiant signet post that was two tone white/red with chrome seporating the color at the bottom body line.
