    1972 911 s alternator

    Hi,
    it seems that i need a new alternator for a highly original 1972 911s (origianl paint). I have received several different solutions. Of course, my first choice would be an NOS alternator, i doubt those are around.
    What are most people doing? Rebuilding? Buying an old rebuilt alternator? Putting in a modern replacement which has a built in regulator?
    Any comments, suggestions, options, greatly appreciated. You can PM me or just reply to the thread.
    Thanks,
    MARC

    You can send it out for rebuilding like new. Then when reinstalled you have your original alt. If you by a new replacement, you will have to update to a alt with a internal voltage regulator.

    I’ve given up on rebuilds, in part because of voltage regulators. The fine threads of the alternators of that era are a pain. I always wanted the proper appearance of original regulators but suffered with overcharging. These are my problems only, I’m sure others have had success. The very proper fitting of internal regulator alternators with their larger coarse threads are robust. The original regulators can be dummied in place and the main non original visual clue is the Allen key in the alternator shaft.
