I concur, INR724 diode bridge fits and works.
Vern, did your SRE bearing look like this? I need to confirm if these are still used.

Following up:
One characteristic of a failing alternator (diode or stator failures) is the high pitched whine that you hear in the headsets.
The level increases with load, so it can be easily detected with wig-wag lights toggling, for example.
As a backstory, I designed and built a video game in the 1970's. As a poor student, I couldn't afford an oscilloscope, so I rigged up my Sennheiser headphones with a series resistor+capacitor to allow me to hear what was happening in my circuit. It is amazing how much your ears can tell you. That was in the days where I could hear the hear the horizontal sweep of the old CRT TVs and computer monitors!

Oh man, I remember that, being able to hear the fly-back transformers. The color TV sets sounded different than the black-and-white, as well.
