I am not 100% familiar with this Camry, bu there goes. Need some more info before you get a real answer
- Is this mirror electric remote control or not?
- Usually there are at least one mounting screw that holds the mirror in place from the inside. I am not familiar with any mirror that is mounted with clips as a primary means of holding it in place. You attach most mirrors by taking a triangular or other plastic piece off the inside trim and then access the screw and holes from the inside of the car. Have you done that?
- Depending on the damage you may need to get a new/used in good condition mirror with new mounting screws. See a salvage yard or a Toyota dealer.
Maybe some of the pro’s here can help more.
