Review on Perfit Zone TOWING MIRROR Replacement Pair for SILVERADO SIERRA 2014-2018: Perfect Fit and Compatibility by Thasapon Bowers

Like the others, I also had a bent bolt. I took it off with a 6mm head and, with an old one in hand, bought a screw from the store to double check the size and cut the head off it. This allowed me to place it in the mirror and then attach the mirror with all 4 screws. The second issue is that the parking lights on the outside of the mirror are not illuminated by the daytime running lights and I believe they are linked to the turn signal on the mirror. . So you have to pull another cable.
