I'm glad you found them 73CB500K2,
I'd like to mention that bryanj has sound advice about your inner collar probably needing to be checked to see if it's with-in specification with a micrometer so that you'll have the correct fit like it had from the factory when new.It would also help if you purchased new outer & inner seals for the ends of the swingarm bearings to keep the grease in once you grease it.
Bob is a good man who does the job well.
