Depends what is needed. NOS or NORS if I can. Sometimes can find older shop with rectifiers and diodes selling on ebay. Stators and especially rotors I'd prefer the right one and the new stuff from WAI / Transpo seems to be only the high current draw '60 amp' rotors. :(
There may be other sources for new that don't retail to the public. Karl has posted there is a place around Chicago that will rewind.

I think at some point I posted photos showing a couple variations of the insulators and output studs for the squarebacks.
Here: Can you ID this alternator?
