Would you mind telling us about your mud flaps in the picture below?
I hot-glued them together with my welder.
It's just a piece of 1" x .125 angle welded to a small piece of square (2"?) tubing that fits over the stinger. I've got a 3/8" nut welded to that so I can lock it in place with a bolt. If I were to do it again, I would use 1.5" angle.
I don't recall where I got the mud flaps, but they are bolted to the angle, and there's some aluminum strap that acts more or less as a 2' washer.

That's about the only photo I have. They work well and are cheap to build.
