Alternator woes

My 1968 Jeepster Commando's alternator finally gave up. 225 V6, 3 spd. It will spin freely with no belt on it, but freezes when spun at higher RPM's. It is a 5 wire system with an external regulator. Would like to keep it stock, or at least as stock as possible. What's the chances of finding a replacement? Does anyone know where one can be found? If I can't find one, has someone done a conversion and know what wires go where? So far I can only find a 2 wire alternator.
Thanks in advance.

 

I would go ahead with a 2 wire easy to do and your whole charging system will be much healthier.

 

can still get what you got,may have to order,and may take a couple days to get it,you got a GM style ext regulated alt right? try and order one for a 1970 chevy impalla 350 cid 4bbl should be exact same thing

 

2 wire set up will be a direct bolt up,with some minor re wiring

Thanks a ton.

 

could look in the phonebook for an alt repair shop, and have them look at it.

 

If you're really wanting to keep the original, they can be rebuilt. We rebuilt several alternators in my high school Vo-Tech class for a local salvage yard, just for the practice.
