Richmond makes a 4.56 for the 10 bolt. I think it would be pointless to put 4.56s in a 10 bolt. That would be a very weak setup becasue of the small size of the pinion gear. Staying focused with the ?, yes it can be done. Also Richmond is probally not the only company that makes 4.56s for the 10bolt.
