Their closet trim clips are the E-body vinyl trim clips, which are similar to the vinyl top trim clips for 71-74 Chargers other than the 71 SE. They list nothing for B-bodies.
These are the one's I believe you need, they are more narrow than the pure "white" ones. I bought these years back by mistake for my Plymouth and the molding kept popping back off. You can always call Tom and ask him also. Ron
