couple of more note. Avoid crank down on the screw super tight. It fits up against sheet metal. Read somewhere that it will bend if you really crank down on it (like with a wrench)

My picture may be a little confusing because the sunroof glass has reflections in the picture. But the edge of the glass to the mounting frames is right where the reflection is. So if you look carefully, you can see how the metal clips extends out parallel to the glass and this is where the top edge of the apron slides in.
