I have done many different things to plug the gap in my old Boss RT II. I have bolted rubber belting on the cutting edges, welded pieces of metal on each cutting edge, and lastly welded a v and half moon piece on my center shoe. They have all worked but they are time consuming. I was wondering if I were to take the center pivot shaft out and have it drilled and tapped would the stock horse shoe like my new Boss V work. I was just wondering if the basic design between the RT II and the new v-plow changed enough that it wouldn't work.
