Duster half vinyl top moldings that go across roof

Trying to picture how these attach......
Is it right behind the rear glass window, up and onto roof, (from each side) then these 2 pieces overlap in the middle of roof?
The screw ends attach to the sail panels behind drip rail moldings. I got these moldings years ago at a local pick and pull.
They are most likely attached to the roof with plastic clips like the moldings for 65-66 Dart GT's. It's been so long ago I can't
remember. Look at pics on the internet for reference.
