Received my black mirror caps today, couldn't wait to get them on so tried as soon as I got home. (note the word tried...) As i'm off to Cornwall thursday so wanted them ready.
Couldnt find a way to get the caps off at all, got the mirror off (easiest way for me) gave up and had tea, then thought no i can't give up. Tried again, a good solid hour later they are on.
Nearly half an hour later on the drivers side resulting in one of the stalk things breaking, sore fingers, alot of talking to myself and removing a spiders nest (hate them!) and they finally went on.
I really hope i never have to change them again. Seriously, never lol.
