Actually, the external regulators are pretty generic. Even one designed for some other vehicle should work if you can figure out the wiring. There's always a field wire, a sense wire, and one for a battery connection. Most need to be grounded for the 'other' connection. All the regulator does is control the field current to the alternator to hold voltage at the desired level. This is usually 13.8-14 volts.
