Yeah, I'm afraid it's a '63 only, car only, taillight. You can get the '64 Dart taillight assy's to work with minor mods but they look a little different so you'd have to change both sides. They're just as hard to find so getting another '63 taillight would probably be your best bet. I think Layson's has some reproduction lenses so you might want to contact Rick@laysons on this site to verify. The factory made two version of the lense. One with a chrome looking plastic trim ring glued to the lense and one without.
