Sorry to say, these are sold, and they are wrapped up in a box. I never did look at the part number, but they are identical to a 65 Dart set I have. The wrapped up ones came from a 65 Valiant. The part number on the 65 Dart vents are as follows: 2277655 3. Hope this helps you. I did not see a difference between the Valiant or the Dart vents. Best. Old Dart 66
