The glass bed in the body is shaped L The clips go against the upright of the L and the gasket goes on the horizontal .
Then the molding has a turned down edge that sits behind the clip.
Now about those clips... Lots of aftermarket vendors sell the same clips for front and back. Those fit fine on the back but The upright portion of the bed is shorter on 67, 68, 69 Barracudas' front glass. The front clips need to be approx 1/16 inch shorter. I happened to have 3 of the OEM clips on hand and gave Mullinax95 one.
I found this little pair of vise grips worked very well for grinding the clip down. Just enough exposed.
