Loose Mirror

The ball end that connects from the stem to the mirror incloser has gotten loose and the mirror moves around to easy.

Any trick to get this to tighten up again? Shove blue tac in the ball join? lol

since the 2 tightening/adjusting screws are not on the outside then they may well be on the inside, if it has that system. that means gettin the glass out without breaking it...that's why i like the ones with the tightening screws on the outside

Thanks, got it sorted now.
