I would contact Messicks' , but here is a link to some info to look at
go to the diagram for 06B01-Final drive, shows a break down of parts and part numbers!
if you look on line I am sure there are free down loadable service manuals too, or a hard copy can be bought some times used off ebay and like pl;aces , showing how to repair things, NEW ones can also be had, but there costly from dealer!
Inner and outer bearings & races are the same. Google LM104949 and LM104911. The inner seal is 19887. For the outer seal and wear ring, suggest getting the numbers from Messicks site and then checking on Worthington ag parts site. They also have an entire kit as an option but not sure what brand/quality of bearings and seals are in it.
