Hello fellow e9ers - Have tried the usual sources with no joy for either the original style of external volt reg type alternator as well as the " 45LX and 42 LX " types with the integral voltage regulators, and nothing seems to be available. Autohaus, FCP, Pelican etc. Walloth and Nesch has very expensive offerings and something on ebay that I am suspicious of ( cost too low, no returns allowed).
Any thoughts as to how to replace this previously abundant part ? Have not yet looked into a rebuild of my existing. I do note that the brush assembly may be available. The alternator I now have is the external voltage regulator type, seems to work on a gross bench test ( produces approx 14.5 V, varies a bit at constant rotor speed, with field voltage supplied by a battery) I have not investigated the alternator internals, and suspect that my external voltage regulator is faulty, all wires are ok.

Thanks

We rebuild. Expensive but you do get to drive your car…….
 
Everyone - Did a home rebuild on the alt - brushes, a bad diode, clean up of carbon and copper, which worked out. Thanks for the help.
Also reset fuel pressure ( had boosted to avoid lean) and redid timing. Then tore around town, first of the season.
