Troy,

Sorry for the delay but since I moved into my house, I haven't been able to find anything charger related as nothing is together anymore. Well, not yet at least. Anyway, here is the manufacturer and part number that was on the label..... Performance Plus sold by Car Quest parts store (NJ) part label number 7015. It is a single groove pulley round back style. Correct for 1968-1969. This is also for a non-a/c alternator.
