Sprayer duals and 22 in hubs for CIH Patriots

I have 4 sprayer tires (14.9s firestones) on 10 bolt rims (46 in) and 4 hub extensions 22 inches long from unverferth that came with sprayer. We run on 30 inch rows, 20 inch rows, and 15 inch rows and dont see us upgrading from a 30 inch row to 22 inch row so have no use for them. Yes its a compete all the way around dual set for a Patriot sprayer (front duals and rear duals) $6,000 for all. Comes with bolts for duals and nuts for sprayer side hubs.
