Can anyone out there tell me if there is a difference in the shape of the side mirrors between a 1st generation and 2nd generation gl1800. I was replacing the turn signal bulb on my left mirror assembly and the screw broke inside of the mirror. I do no want to have to buy a whole new assembly when I only need the glass. I own a 2012 wing and have seen on ebay where there are just the mirror glass for sale but state they are only for 1st generation. Thanks for any help.
