I need help putting on Edge Cut mirror on my 2013 Streetbob brake side or right hand side. Yes mirror lol. The stem is square and therefore it hits the brake fluid housing. The stock mirrors have a round stem and they are connected to the turn signal and can be twisted on. The left/clutch side is no problem because it doesn't connect to the turn signal.

 

Are they polished aluminum?
If they are you can sand them down and polish again so they will clear the reservoir

 

One option is a small chrome spacer, you can get them pretty cheap at ACE hardware, you can see the one I have on mine in the pic. They have several sizes in the specialty bolt section.

 

I had a brain fart while riding today and got it done. Just switched the adapter from left side to right and done! I wonder if that was the way it was supposed to be originally and the dealership put them on backwards. lol
