Thank you Zed Head!

A new one is $80, errr reman...

Maybe I could change that out?

You all remember the commercial where the guy was trying to drive a square peg into a round hole, and his work mate says "hit it again!".   Funniest commercial ever.  

I've learned from this forum to "ASK, somebody has done it a dozen times".  I'm glad I ask. 8^)

You'd need a soldering iron.  And you'll probably find that the brushes are worn when you take it apart.  I only suggested just to show that the parts are available.

You can get the other parts on Rockauto too.  Probably find a complete kit on eBay.  Or, if you have a shop in your neighborhood they might be able to get the parts and do the work.  Just saying, it might be a better option than taking a chance on a parts store reman.  You'd have a real professional taking the time to do it right.  The parts are available and that's usually the only limitation.
