I thought it was just a case of unscrewing the fixing nut underneath the wing - this mirror has some sort of plastic tubing projecting down from the nut, which doesn't seem to move. The nut won't unscrew because of this tubing, and the mirror arm is sprung to the mount, so any force on that just "unsprings" it. can any one help me on how to remove this mirror from this very meagre description?
thanks
