Identify crank pulley 1971 360 from Chrysler

Mine is 5 1/2 inches in diameter and only 2 1/4 inches tall - lines up with the crank groove nearest the radiator Non AC water pump pulleys are 6 3/4 inches in diameter and will not clear an AC 3 groove crank pulley. You can't really measure these things without taking them off the water pump. Measure height by putting the pulley bolt holes down and measure up to the top of the pulley
