2 destroyed starters in a row...WTH?

Do you have as much power as before? And a vacuum advance can advance the timing while cranking if it's plugged into constant vacuum; with the throttle closed. Off idle vacuum can do the same thing with the throttle slightly opened; just not as easily. I just always like to know the "why"..

Power is all there. I smile just thinking about it ha ha.

Yeah, I suspected it might have something to do with the VA, but the 2nd time it broke the Vacuum line was disconnected/plugged. Have only ever run the VA from the "Timed Spark Vacuum source" (Holley 750) but I hear what you're saying.

Stuff like this is never a bad thing if you learn something (or lots) along the way.
