Rear axle is wider on a dually, you may be able to reuse it but the tires will stick out further in the rear than the front. The rear is usually narrower to aid in turning radius. I don't know on the front if its an adapter that will unbolt or you would have to change the hubs. On Fords its changeing the entire hub, I don't believe so on Dodge and Chevy?
If you were closer, I have all the parts to convert yours.
