1965 Mustang vent window frames
Brian, thank you so much for your help!!!! I looked and looked and couldn't find a round hole! When you sent the latest photo of the door, at least I knew the area to look. Still nothing! Then I noticed a small tear in the area and there it was!!!! The hole was covered by the paper barrier on the door. The door panel had been taken off to paint the car, so the paper was there but painted body color. I cut through the hole and there it was! I feel pretty stupid, but not any more, thanks to you!
