My wife comes home says, "Hi, my rearview mirror fell off." I say, "Yeah it looked like it was close last time I was in your car, I got some glue for it yesterday." Her, "oh cool." So then we needed to leave and we take her car. I get in and say, "I thought that piece was gray aluminum I wonder why it is black...owww, it's sharp...HEY...WTF...it's glass...where did glass come from...ohhh craaap.

There's yer problem!! That's not glass, that's UV membrane that holds the pieces of glass together when people start chucking cantaloupes onto the highway at night.

See the thin layer glass on top of the dongle (does it have a name?) that mounts to the windshield.
So it is windshield #3 for this car, no the cantaloupe thing was not a joke!!!
