Yes, that will take the side sway out of your multipouint draw bar and will keep the blade from moving side to side while in use. Be sure to purchase only category one parts. I once broke a lift arm because the elevated blade swung to the side too hard..
But those will do nothing for vertical stability. For that you will need the four piece set of flats shown above.
Look on the bottom of your fender mounts, under the axle for pins to attach the ffront of the sway bars. You might have to buy brackets and pins for the front of the sway bar. The brackets are retained under the axle by the fender bolts. The pin is a little short thing about two inches long. Yesterday's Tractor and Steiner are dependable sources for any parts which can not be sourced locally.
