first you'll have to trim the bottom section that curves back under the bike. then you'll have to drill a couple of holes in both the pan and fairings for mounting the dzus fasteners. i also have a single nut/bolt that holds the chin piece to the front of the belly pan and then the rear is loosely supported by safety wire.

those are my stock fairings that i trimmed to fit. not perfect but good enough for the track.
