I picked up some parts from the RockAuto closeout sale listed here : http://www.fiero.nl/forum/Forum4/HTML/061818.html
The pickups were almost completely warn down.
I do have one question, on the windings, the inside is very rusty. Should I just sand this too, or should the entire windings be replaced?

I would knock off the heaviest part of the rust with a wire brush (or wire wheel in a drill motor) and treat the rest with Krud Kutter The Must For Rust available at Lowe's or Home Depot. Krud Kutter is a rust REMOVER and INHIBITER.

Im sure you allready know, but your going to neeed a large paper clip or nail to hold the brushes in (theres a hold in the back of the case for this),when putting the case back together.

tooth picks are also good for holding back the brushes.
one thing to bear in mind - if you intend to paint the alternator make sure it still grounds with the car or you will see the charge light come on.
I found this out the other year and ended up using a ground strap from my top bolt of the alternator to the dog bone bolt (btw the alternator brackets had also been powder coated)

What size bolt holds the pulley on? I don't have any sockets that are large enough.

Well it's been incredibly ignored, but I finally got around to punching out the bearings. The shield stayed behind however.
I was also able to use a vise at the Baltimore Node hackerspace to get the 24mm bolt off. Still struggling to get it fully disassembled however.[This message has been edited by no2pencil (edited 04-30-2014).]

do you have a source for a higher output voltage regulator?
(I get confused, the voltage regulator controls amp output right?)
ive purchased both completely new and remanufactured stock alternators for my v6 fiero and they don't last anymore than a month or two before they "pop" and stop charging at 13.5-14 and start staying around 12 or so. its of because the alternators "duty cycle"
the alternators I've gotten cant hold upto the headlights and ac being on with a standard aftermarket radio setup (head unit and better speakers).
I've found some aftermarket high output alternators out there that would fit, but I'm sure most of us here are mechanically inclined, so that is why I asked.
I'd like to rebuild my working alternator, and just replace the voltage regulator to increase the power output.
