Go see your favorite old-time alternator guy, or ask the kids with the
really loud stereos where they go for alternators and you will find a
qualified alternator guy.
I put a little alternator from a 70's civic in my Triumph TR3. (the shaft
was the right size for the pulley and it was only 35 amps, perfect for not
having to modify the system much) It did not have an internal regulator.
My alternator guy found me an electronic regulator that even had a
connection for the alternator light and cost all of $30. Works like a charm
and was small enough that I could gut an old TR3 mechanical regulator
housing and easily drop it in there. The regulator was about 1x1x0.5 inches
in size. I would have do to some serious digging to find the paperwork on
it though. It's been in there for years.

For the ~30 years I've been playing with vehicles, regulators have been a
mysterious black box to be immediately replaced (right after the battery) if
anything is wrong with the charging system. I have a 6v Italian motorcycle
that charges at 10v, maybe higher but I shut it off to not kill the battery.
Is there a reason they can't be tested and/or replaced with any other
regulator of similar current carrying capacity? I mean, I'm sure mine is
toast
since it grounds through the frame and I ran it with all the mounting bolts
loose for a day. But it looks like an original replacement isn't available,
so why not a tractor or Vespa replacement?
