He claims he's run it for a couple years with no noise or issues so that is pretty reassuring.

How about just using a CS-144 alternator? They interchange on the stock Pontiac brackets and come with a serpentine pulley. I have a CS-144 on my '66 GTO and retrofitted a Vee pulley. Still have that serpentine pulley somewhere... need to look at it. As I recall, it has the same offset as the Vee pulley I used, which came from an early 80's FWD GM car. CS-144's came on all LT1's, Cadillac Northstars, and others and seem to be one of the more durable alternators GM made. Here's a pic of my '66 showing the CS-144:
