Regulator must have a post for the field coil wire. If you install a regulator without the proper configuration or is a B circuit regulator this could fry your generator. The Autolite 21732 may interchange but may still need to have voltage adjusted. I don’t know if is a B or A circuit regulator.

If generator field coil lead is connected to the insulated brush at the back of the generator it is an A circuit.

I field coil lead is connected to the grounded brush or  connected to generator frame itself it is a B circuit.

If incorrect it is easy to see how things could melt down. I learned this the hard way since a generator man with limited knowledge cooked my generator in the past. I had to dig this old knowledge up since most of these old generator guys have ridden off into the sunset.
