i had some polaris mounts with some other type of guards but they eventually broke off from rolling sled over.
i have given up on this as well as trying to keep the stupid sway bars on those only last me a about three rides before something breaks on those.
I used a set of rox on my assault I put the brake side the same as you guy saw in the earlier post. The throdel side I trimmed the wire cover on the throdel block and flipped the rox mount upside down.
