I replaced the regulator with an Americian made one last September. It died tonight. Oredered another and will discuss replacing the bad one with the seller. Really don't want to go to an alternator unless I have to. Is there and electonic regulator out there that I could possibley hide in an orgina regulator housing or a source for a rigulaor that will last for more than a few months?

I had similar issues with my 55 TBird 12 volt system.  Went through a number of generator rebuilders and assorted problems. I know you don't want hear this, but it's time to convert to an alternator.  Generator rebuilders are dinosaurs. I used the Casco alternator kit and I couldn't be happier.  My old voltage regulator is still in my car for looks.  Keep the original parts for the next owner and keep your sanity.
