1972 dart 2 door

So I got a donor set of doors for our dart . They now painted and ready to mount and I realized there are holes for trim at top of the door right where up to the felt . I've never seen a car with this and rest of my car does Not have this no photos I can find show it . This was **** of my donor doors I had just before I took them apart.

Anyone know what this trim is ? How I can get it for my back window as well ? Because I need make them match now. Second photo shows the holes after being primed . I've had many a body's and never seen this . Not a single photo I've googled shows forks with this .
