They custom built them for me after a series of emails back and forth with measurements and pictures, so they should still have that info. They charged me $60 for the rears and $40 for the fronts, since they don't have a regular demand for that model. The rears alone could possibly allow the engine case to still scrape a little and the fronts could make a low pivot point to allow the bars to hit hard. This is why I went with both front and rear mounts.
The one thing I didn't notice before is that the right rear mount is inset about an inch so it doesn't stick out past the fairing like the left side, but 5-1/4" is the longest slider they'll offer. It is still flush so it will perform its duty in a slide and in combination with the front slider should keep the fairing to minimal scratches.
EDIT:
Also, the each of the rear sliders will require an M10x100mm x 1.25 pitch Socket Head Cap Screw, which they should have. Each of the front sliders will require an M10x120mm x 1.25 pitch Socket Head Cap Screw, which they didn't supply. I had to order two from yoshimura as a result of several searches. That size was a bit tricky to track down.
