I have the water pump pulley, but not the crank pulley. $20 if you can use it.

i think after looking a bit i just need right crank pulley !

If the grooves line up, most people elongate the one hole that is off and bolt it on with no problems. The pattern was changed in the early '70's, I believe.

'72 and newer were evenly spaced.....71 and older had the one hole staggered. The replacements from Chrysler had the one hole slotted so that is no problem on doing it. Leaving one bolt out will throw off the engine balance slightly.
