Thanks so much. I think I'm pretty clear on the mounting, except for one thing:
This tab:

How much space exists between this tab and the fairing itself? Is there some kind of spacer?
I'm confused because it seems like -- if you were to tighten the screws (the ones on the sides of the headlight on the front of the fairing) to the point where the bracket was touching the fiberglass, the headlight would be sticking waaay out past the front of the fairing.
The headlight bucket setup I have is an H4 version and looks pretty similar to pics I've seen of the Euro unit, so I'm assuming that's what I have.
Just trying to understand the relationship of the brackets to the inside of the fairing, I can't for the life of me find a pic of how they are mounted. (my fairing is unpainted and lacks holes so I'm trying to figure out where to drill 'em, also).
