This might sound petty but my wing mirrors flap back when I go over 50mph. Is there a quick fix/tighten? It's just the mirror glass part, not the door bracket. Can't see anything obvious.
If they are badly rotted and ya havent got any money. Break a hacksaw blade in half, drill through it, rivet the bottom of it to the mirror arm and rivet it two or three times into the mirror backing, job done !
