1967 Dodge Dart Gt clips
I thought there was a rubber seal that goes in the body hole before the two prongs but the 67 dart I just took apart had nothing like that. And there was no indication the rocker moldings were ever off.
The way these work is you put them against the body and squeeze the two fingers together, the fingers in the hole spread apart and " lock" to the body.
In my experience once they have been removed they do not lock in well the second time.
I plan on either adding a screw like the type that attaches the wheel well trim to each clip or using panel adhesive or 3m double stick emblem tape to make a more positive attachment.
BTW 63 Ford Galaxy clips are almost the same and are reproduced only difference is each has a small tab on the top and bottom of each clip
