Assuming you also have Dexter axles there should be a serial number printed on a sticker somewhere on the axle. You can contact DExter with the number and they should be able to tell you exactly parts are needed.
I would also have at least one inner/outer bearing and raceway on hand. You never know what you will find once you pull the hub.
I assume you already know your way around working on hubs and bearings.
