I was going to do that Jack but I couldn't figure out how to get the mirrow off :p
As you said though when the mirror was folded in it stopped clicking so I just went ahead and severed the wire which allows the mirrors to be folded in by a switch and it did stop clicking while still allowing everything else to function but the fold in mirror switch of course.
I would recommend your method to anyone over mine as who wants to break something instead of fixing it haha? I just had no patience left after fixing the fans, clutch and replacing brakes.
I must admit though I'm VERY happy this stupid noise is gone now though haha!!!
