I made brackets that fit behind the mirrors, and used existing fairing screws to mount. I made mine out of .125" aluminum plate, and mounted them so they would exit below the mirrors. I did have to trim a small amount of plastic from the bottom of the mirrors.
I will look to see if I have some old photos. I don't have any measurements. I just pulled the mirror and made a cardboard template. I used the template to rough out the aluminum mounting plate, and then just fine tuned it to fit the way I wanted it. Then made a twin for the other side.
Google is showing me a driving light at the bottom lip of your fairing.. are there bolts on the underside you could use some aluminum bar stock to mount to and tuck the driving lights into the fairing (in front of forks, but out of the way so you get full suspension travel and the like?
