I had a feeling it was a clip of some sort. What made me stop was that the OEM door panel flexes when I press on it around the window crank. With the aluminum plate, I felt I would have much less flex which may not allow me to slip the ring behind. Now I am curious.
Yes it has to flex in a little to get access to the clip behind. OEM, it is just particleboard; plastic if it is a high end refurb piece.
