Get the bearing on ebay, and buy a used one if that is all chewed up. Then rebuild the used balancer.. Bearing number 16007
If it was jumping around that bad, I would be concerned you case is egg shaped on the clutch basket side at the bearing bore and the bearing will fit loose even if new. You may want to check that. If so you need a new/used case side or Jason hall can bore them and fix them last I heard. also replace the left holder bearing too.
Here is where my long useless list of stuff nobody cares about should go...
