They are crap. Garbage. The steel scratcher tips wear through the plastic mount in days from vibration. Hit any kind of ice chunk, get skid in a rut, trench into the unknown, and these cheapies will bend/break. Even without rough stuff, vibration will cause the cheap plastic mount to wear right down to bolt, which is also crap. Buy some good mounts, and use fuel hose over the scratcher tip to keep it from wearing through the mount. Use a hardened bolt, the ones used for XS idler wheel axles are excellent, correct length and diameter, you just need to grind away the flange so they fit into scratcher mounts.
