Default Voltage regulator diode

According to the manual 1966 vehicles with a factory 63 amp alternator should have a diode intalled inside of the voltage regulator between the field and it looks like the ground. This is because the 63 amp alternator has a 4 ohm field circuit. This is shown on the mechanical regulator only, it is external on the transistor one. I am replacing the regulator and cannot find any regulator that has this diode or any reference to it. I can easily add it if anyone knows any specification on it or where I can get a regulator that has one installed. It looks like it is just used as a flyback, I can take a guess but prefer to know. Any ideas?

Any 6 amp or larger rectifier diode will do the trick, you can scavenge its equivalent out of old electronics or buy 50 new ones for $6

You might consider installing one of the solid state conversion kits in your original. Your alternator output will be much cleaner and it will look completely stock.
