OK, I've searched, can't find it. The passenger side visor holder is about to fall off. I can see there's what looks like a removable cover on it, but it's about impossible to see since it's black against black against black panel. How does that cover come off so I can tighten the screw? Just stick a small screwdriver under one of the sides and jerk it off? I'm sure it will look great when I'm done.
