I got new door glass felt rubber for the sill and the top frame of the doors for my 83. So there is a plastic xmas tree pin that goes in toward the upper rear of the door and a spade shaped metal tang that goes towards the front corner top near the vent window. My issue is i see nowhere to put this metal spade in the door frame. All of the videos from and Brothers show these guys just popping this in without a thought and no visual of anything. Anybody have a picture of what this is supposed to clip into?
