I made my own, patterned after the one in CSX2259. You have to be extremely careful about the length of the mounting screws that go into the windshield frame - 1mm too long, and your windshield is toast.
Took several trial and error attempts to get the angle just right for the rake of my laid-back windshield. I had to put slotted holes in the base of the bracket to be able to tighten the lower screws to the windshield frame.
regards,
Jeff
