I personally have had two of the new electronic voltage regulators in vintage housings (left one) fail and peg the alternator. I managed to pick a NOS unit at Carlisle (right one) which fixed the issue, but it won't last forever. I would be interested in a new unit if it could be installed in a vintage housing.
I bought one of the Mopar vintage looking ones (in the black electronic style box) after buying a parts store one ( it wasn't worth a crap, 20 bucks out) and having the one on the car go to crap....
