In addition to Novaderrik's comments, internally regualted alternators regulate the system voltage better than the old buzzer style regulators. This is particularly important with electronic ignition systems. Mallory is one example of an electronic ignition system that will fail if hit with a voltage spike or excessive voltage. Another benefit to the CS130 alternator is that is produces much better idle amperage that any of the other types. That is important news if you plan on running electric fans or other high current accessories in the future. IMHO, there are more reasons to switch to a CS130 than stay with the vintage setup.
