Hi brian brown. Good luck with your new Argo, I have met Argo dealers at the ottawa Sportsmans show who were very knowledgable,. Building your own plow is easy and many guys do it. I suggest that you start by buying the correct extension plate and bolts from an experienced Argo dealer or one who will look it up. My dealer showed me many different ones for different machines. You do not want to change the dimensions of the bearing flange and you want it to stay waterproof. Non amphib tires seldom swim very well if at all. Good luck. Maybe we can meet on a ride. I ride mostly in Prince Edward County but I have ridden in Peterborough, Tillsonburgh,Brockville and Ohio this year. Good luck
