i am gona go out on a limb and guess as i have only seen one 2011 slingshot board with my own eyes (without boots.)
judging from the pictures from the video (one with the bolt sticking up. and the other with the Cap screwed on)

the bolt will come up through the hardware of the boot/binding from the bottom. the bolt looks long enough that it ought to go up and through CWB (and other brands) hardware pieces. The tricky part is capping the top off so the boot stays tight and secure. the provided capping piece may or may not work with some other brands without sticking up a lot. Or maybe the provided topper wont be wide enough. you may have to use a different nut or something from the hardware store to cap it off if the provided one does not work well.
BUT AGAIN, this is a guess educated by mostly looking at a video and pics
