Duster quarter glass Mylar mount strips

I need the part that attaches the front of the Duster pop-out quarter glass to the pillar. (Often sold as an early A/B body "door glass channel run.")

Poster "dadsbee" mentioned an older Mylar piece that was bad for its intended use on the back of A/B-body vent windows, but works perfectly on Dusters-if anyone has that laying around, that would be great.
