70' Dart vent window housing removal

what holds it.. looks like one bolt under rubber and it just slides off the bottom stud? like to know before I start. Also the door window glass flops around. What holds it in the front channel of the vent window housing. Whatever it is I'm missing. Any pictures/diagrams would be great.
There is a bolt under the rubber on the front for jam and there is a clamping set screw that you access from the door window molding on the inside. Look just below the wing window and you can see where the clamping screw can be accessed. Here are two pictures of the removed frame.
