'72 was the changeover year for the pulley bolt pattern. Went from asymmetric to symmetric.

Double belt alt, probably an AC car, with power steering. There is a change in the crankshaft bolt pattern between the years, but I don't remember when that happened.
Finding the numbers on it would tell the story. Probably fits a lot of years, body, & motor configurations. Me thinks not, no provision for driving the alternator  All the BB cars with power steering and air conditioning I've seen had four groove pulleys  Maybe for a car without power steering with air conditioning
