Default HD Alternator?

My 69 GTO was ordered new with HD Alternator. PHS reads "ALTER - S/R - 55". Is this an externally or internally regulated alternator? How does this differ from the standard alternator these cars came with? The car no longer has the original alternator (now has an internally regulated alternator with a hacked up wiring harness), and I'd like to replace it with the correct one. Thanks, Will
