I have pulled the regulator from my "spare" '84 and now see how the whole 
process seems to work.  The brushes are integrated into the regulator for 
a convenient (for an Audi) swap.  I will install it tomorrow and see what 
happens.  If it works, I may install new brushes in it for good measure.  
How long are they supposed to be?  Where might I obtain the brushes for a 
next to nothing alternator revival?

Should the brushes and other surfaces be cleaned with anything like 
contact/brake cleaner or should I just leave them alone?

You know, If it ain't broke, fix it, but don't spend too much on it...
