Review on Enhance Your Golf Cart's Safety and Style with Moveland Universal Side View Mirrors - Compatible with EzGo, Club Car, Yamaha and More! by Jim Martin

The first is good, the mirrors are just excellent for little money. My instructions said to use an 1/8" drill bit. I assumed it was for the fake self tapping screws used when you don't want to drill through your steel studs completely and use the screws provided. The first screw let itself do not tighten by hand or with a 1/4" impact wrench. The sticker on the screw was cut off. I took it out. The included screws require a 1/4" drill bit, which isn't mentioned, but I have 3 so that's not a problem. Drilled the holes and screwed on the mirrors with no further fuss. The mirrors pivot and adjust on a spring-loaded ball that has not been tightened enough. ex works. A small metric deep head can tighten the mounting nut to provide increased tension to prevent the mirrors from moving out of adjustment. I forgot the size but it's close to our 3/8 inch and be sure to use the metric.
