I slipped the windscreen behind the existing black plastic fairing and got it lined up to where I wanted it. This is where I figured out I needed to trim the "wings" on either side to keep them from hitting my hand guard mounting bar. I clamped the shield and the fairing together (small c-clamps, one on either side), and brought in the 1/2" gap on either side (it might have been a bit less, the center portion from the V was flush until you got out toward the sides). Took a paint pen and marked my drill holes from the inside. Removed the headlight assembly and drilled the holes. I did really small pilot holes from the inside, and then the full size holes from the outside. Bolted the windshield to the fairing. Re-installed the fairing with windshield attached. Installed the clear p-tube on the cut wings.
