It's par for the course, the vast majority of aftermarket bodywork vendors, such as Airtech, go out of their way to tell you that you are on your own when it comes to mounting their stuff, even with bikes that they have themselves built. I once contacted someone (who shall remain nameless) who makes an MGS01 replica body kit, who had all the parts in stock and ready to ship to me, but could not provide any details as to what the hardware would need to be, even though he had built one himself and has photos to show. I found it really hard to believe he didn't have any drawings or any other documentation or measurements he could provide, and decided not to buy it because it pissed me off so much.
