Where to buy correct alternator for a 1969 340 swinger non a/c car
See if you can get a used one that still has its original rear bearing. That would be a decent roll of the dice that it may have its original rotor and stator. Even if you need to get them rewound, you'll have the correct item for them to copy if you explain what and why you want it so.
Ideally you would want pulley 2444 478 and an alternator stamped 2642 944 or 2098 850 (which hopefully will have the pulley still installed).
There's probably some other part numbers from earlier years that would also be OK.
