Can you identify these?

OK, I know, I should have taken better notes, or more pics . . . or both.

I took the car (1967 Dart 270 two door hardtop) apart four years ago, and I've slept since then. Fortunately, I remembered where enough of the parts went to successfully get most of the car appropriately rebuilt, modified, reassembled, etc. to get it on the road. I still have a lot of work to do on the interior though. I found these four (large - about 1" wide, and a little longer) clips in one of my bags o' parts, and can't recall removing them - so I have no idea what they are or where they go. They look expensive, though, so I'm guessing I'll be glad I don't have to replace them. Ha Ha.

Does anybody out there know what they are? Since they were in a box with some other rear quarter window parts, my best guess is that they have something to do with the upper filler trim panels for the quarter window, but I can't see where they fit.

A little help here?
Thanks.
