68 gtx rear window interior mouldings

[68gtx]

new to the b body world, have a question, how do the rear window interior mouldings attach to the interior, got some supplied with my car but they were not installed? is the rear window supposed to be urethaned in or is it supposed to be in a rubber oulding like the front window? mine is urethaned in. i am thinking maybe the tubber has a notch for this moulding? anyone have a pictures? help?

thanks in advance

Window is installed with strip calk or urethane. Int moldings from the top down around the sides attach by pushing them onto the healiner barbs. The bottom int. molding is attached to the package tray.
I have a set of barbs if yours are missing.
