Where the heck do you walk into an auto parts store and just pick up a set of brushes in stock for $2.12? I've called all the major and some of the minor parts stores in Portland asking about these things, and nobody I've talked to can believe somebody is trying to just get brushes for the voltage regulator.
I've bought these brushes online and done this job two or three times. It's great. Thanks for the writeup.
