I contacted the company that used to sell the 90 amp alternator stators for 22r and 22re engines. They no longer sell them as there wasn't nearly enough demand. They were kind enough to give me the contact info for the company that actually makes the stators.

Broadway Electric in So-Cal. 7825 North Ave in Lemon Grove, CA 91945. Spoke with Rick. Super nice guy who was very helpful. Phone is 619-461-4555.

$55 plus $8 shipping for the stator. They apparently do all sorts of alternator and starter stuff.
