I went to Honda parts to get a quote and they asked $485 for the regulator and $46 for the brush, I thought they were joking. Then I went to Ashdown in Sandown, got the regulator for $55 and the brush for $19.53. The conclusion is “DON’T BUY FROM HONDA PART” they are crazy.

When the brushes are worn and the voltage is unstable as in it fluctuates between 11-16V in sync with the rpm

You should probably change the title to Alternator, regulator and brushes replacement rather than Alternation Rebuild... As you're not actually rebuilding or reconditioning it
