Wing mirror troubles

[mickvp]

I normally leave my bike parked up with a cover over it, but I fold the wing mirrors in to make it easier to get the cover on and off. Well today when I went to unfold the wing mirror the pivot pin only went and snapped and the bugger came off in my hand.

Can I just fire a bolt and nut through where it pivots as a repair? Even if that means I will lost the ability to pivot this one?
