Hi-Lift makes a tube mount for bull bars and similar mounts. The jack makes a great bumper but sucks as a jack especially after it fills with trail dust. They make a neoprene cover but I've gone through two and at $70 each, they don't last long on the trails. Note; keep the zipper on the neoprene sprayed with lube like wd-40 or it won't open. I had it on the 500 before moving it over to the 1000.
This may get you started in the right direction. I’ve seen this used on other sxs brands and Jeeps. A couple of U bolts, large washers and wing nuts could get you mounted for $10 - $15. Exhaust clamps from the auto parts store would work the same way and probably be stronger.
