I still have the tabs to hold it in place, but the plastic appears to be broken on the right side when the clip would catch. Anything I can do to repair it? It keeps popping out while driving, and I'm afraid I will lose one of those clips and never find one again.

 

Super glue. That's what I did, just glued the metal clips in there. Holds good.

 

Wont melt the plastic?

 

Nah, nothing to worry about. Get the gel super glue.
