The Delco 10SI and 12SI are very similar alternator. The difference is the 12SI was designed for higher output and so has better cooling. The rectifier bridge has a bit larger heat sink. The rear frame has more ventilation slot area. The fan is more efficient at moving air.
When replacing a generator with an alternator there really is no advantage to using a higher output unit since even the smallest alternator will put out more amps than the original generator. The biggest problem with those alternators on farm equipment is vibration. The 10SI alternator is available with swing brushes rather than the original sliding brushes which greatly increases their life and pretty much eliminates the brushes hanging up in the holder. I have seen 12SI alternators with the swing brush assembly but what they are is the rear frame, brushes, and rectifier bridge from a 10SI mated with a 12SI front frame. There is not much advantage to that unit unless you are looking at a 100 amp unit.
