I dont know if the bushs are available for these old 8 tooth Boschs, but given that you can buy either Valeo or Nippon Denso 8 tooth starter motors nowadays I would go for replacement.
The bushings are available several places. Motorad Electrik comes to mind.

The only part that I think I see reports about not being able to buy is the early 8 tooth pinion. These reports are rather universal however I'm not really sure that there isn't some obscure source, it's a Bosch part after all, or there isn't some way to make do, adapt, another 8 tooth pinion to the Bosch starter Armature.

If you need the 8 tooth pinion it doesn't look hopeful.
