If you call Windvest directly, I'll bet that their customer service person (the owner's wife, I believe) can get that answer for you.
BTW, I have the mounting brackets for the 16"X16" Clear, which came off of my Honda VTX C model. If you find out that it will work, I know that they will sell you a replacement screen at a pretty decent price and I'd be happy to sell you the handlebar mounts for a very attractive price. They are in pristine condition. I also have their leather pouch which is made to go behind the screen, suspended from the mounts.
