I am looking for a shorter windshield for my Cross Country Tour. From what I can see the only one that uses the stock brackets is the 7JuRock. The other choices are getting Madstad brackets. MY question is do any of the other windshields that mount with the smaller brackets sit on the outside of the fairing like the stock tour windshield.
The brackets that come with the Tour have six bolts to hold its extra-tall stock windshield in place. Those brackets, in turn, bolt to the bike's metal (underneath the curved black plastic part) with four bolts. All you have to do is remove the Tour's windshield and those special brackets, set them on the shelf, and you have -- for windshield purposes -- an XC, instead of an XCT. That is, a vast array of aftermarket windshields meant for the Cross Country will now bolt directly to your Cross Country Tour.
I knew from sitting on the bike and demo rides that I did NOT want the stock Tour setup, because I'm a look-over, not a look-through, rider. So when I ordered my XCT in 2012, I had the dealer put on a KlockWerks Flare, instead of the stock XCT brackets and barn-door windshield. (The bikes come crated without any windshield on, so the dealer has to do prep work. I had to pay for the Flare, but no labor.) I put the XCT brackets and windshield in the car, my wife drove home, and I rode the bike home. (I later sold the brackets and windshield, and bolts and washers.)
In addition to 7Jurock and Madstad, and Klockwerks, you can get windshields for the XC/bracketless-XCT from Vic itself, Gustafsson Plastics, Clearview, Cee Bailey, and some others that escape me at the moment.
The Flare I had (and sold) fit behind the upper fairing edge. The Madstad (that I now have) sits above the fairing. I'm not sure why you're concerned about how an aftermarket windshield fits. Much more important, IMHO, is how a given windshield affects buffeting and how it provides protection or cooling. That, in turn, will depend on how tall you are, your torso length, what kind of helmet you wear, what kind (if any) lowers you have, and so forth.
FWIW, I thought the KW Flare looked nice and worked well for my 5'9", 30"-inseam, height, but not so well for shorter or taller riders. I have an 11" Madstad and their brackets, which is adjustable and works well for me, too, but a lot of folks think they're fugly.
