The clips are plastic, kind of fish shaped. They slide over a headed stud. The rear corners of the trim have two pins that go through holes in the tops of the rear quarters below the rear window. Speed nuts go onto these pins. Two piece chrome, joined in the center of the rear window. One piece slips inside the other. Both sides end just short of the drip trim. You can see maybe 1/4" of non-covered vinyl top right there between the drip and the rear chrome. If I ever make it near my coupe soon, I could take measurements. The plastic clips could be screwed down if the studs are missing. I have an xtra entire set of trim, clips, speed nuts, etc. if anyone is interested...
I used to be indecisive. Now I'm not sure.
