As I stated above the picture.. NO setscrew.. none.. nowhere.. nada.. you thread the hole and insert ball stud.

From my install --- > Got it loose and tapped easy enough, screwed the ball stud into it, and actually put blue locktite on it and just tightend down against the base. Had to custom contour on one side of my CCTV mini bracket radius as it wanted to lay against the windshield. Raised the mirror higher than my normal viewing pleasure, tightend the bracket down and moved the radar detector into position and adjust the mirror down to my proper angle, which snugged it against the detector.. should prevent any bounce rattle that way.


I did not "add" a locking nut - Like GG shows in his on the back of the mirror.. Just tapped the hole.. started the ball mount into the hole.. and put mirror back in place. Put the locktite on and screwed it in by hand till it bottomed out against the windshield mounted bracket.
