I'll give an alternate source that I used to get parts to rebuild my alternator several months ago.

You might want to do a search here on a thread I did about rebuilding my Montero alternator. On mine I had to buy a 200 watt soldering iron (Amazon) to de-solder wires to get at the rebuild parts. I also needed a bearing splitter/puller for one bearing. The brush wires can be de-soldered with a standard soldering iron.

I recently rebuilt a Toyota Denso alternator which was much easier to dismantle and rebuild than the Mitsubishi.

The price of rebuild parts is way cheaper than buying a reman alternator.
