Identify crank pulley 1971 360 from Chrysler

remember that the water pump pulley for the AC cars is much smaller in diameter and much shallower than the one for a non-AC car. I mean really small in diameter. It makes the water pump spin faster to flow more water in the 3 core radiator that rounds out the package.

I have the feeling that you had to get power steering if you had AC, other wise there would be no adjustable pulley for that outer WP/PS belt.
