So I found these on amazon and ordered some as I've been searching all over the inter web for a clean way to mount some aux lighting to my ROPS. I figured I'd mod them if necessary but to my surprise, they fit perfectly. Just plain perfect. They slip on with almost zero play. Both halfs are tapped with a 1/2"x13 hole in its center and are well made. I feel that they are far superior to the u-bolts and band clamp style brackets I've seen. Hopefully this helps save others some time.
