I have a 2004 Avalanche Z66 with 287000 plus miles. I have always had problems with the rear view mirror falling off. I have had professionals as well as myself glue the mirror back in place. The last time the mirror fell off, it took a piece of glass the size of the mount from the windshield. I used an epoxy to try and glue the mount back on but that only lasted about 2 weeks. Are there any suggestions on how to attach the mirror back in place without replacing the windshield? Is there an after market plate that can be used?
