Having not seen one in quite some time, it is flat on the bottom of the clip and the top is flat but has a 90 degree bend down to where it snaps together? I believe the vertical piece snaps together where it meets the bottom?
Hmm, wish I would have looked last time at the junk yard. Looking through the ash tray area I can only see that it clamps down over the sheething and is held tightly to the control panel. Can't see how to release it.
