Thank you for your response.
I can get the front bushing here
for about .99 (the one in the trans bellhousing).
I was wondering about the one at the back
of the starter, inside the cover plate.
Mostly, though, I was looking for a source for
the carbon brushes. Off-the-shelf, as it were.
Having found a "DIY StarterOverhaul" on VW Vortex,
I thought that might keep me occupied during the
long, boring winter months.
Perhaps I should do as you suggest and check out
either a welding shop or an auto-electric rebuilder.
So long as they don't insist on re-building the starters
themselves, which would , somewhat defeat the purpose.
Thank you for your suggestions. It's much appreciated.
