    What part number:

    1970 Pulleys without A/C should be:
    Water Pump # 1375141
    Crank # 1375142


    1970 Pulleys with A/C should be:
    Water Pump # 1375146
    Crank # 1375143


    1971 & 72 Without A/C should be:
    Water Pump # 1238156
    Crank # 1235779


    1971 & 72 With A/C should be:
    Water Pump # 1235778
    Crank # 1235777


    71 & 72 Motors with A/C would have the LONG Shaft Water Pump

    I thought I was going to find a pic to see where the number is, no luck.
    Can you tell me where the number is?
    Thanks

    Do you have a long or short water pump?
    I have a 70" Skylark with 71" 462, short water pump, 70" ps water pump and crank pulleys. I'm 1/2 in 1/2 out of my TA fan shroud (70") . There are a lot of variables. Jim

    I have electric fans, manual steering, no AC.
    It’s a hot rod.
    Long pump.
    Cheers

    Bigpig455 Fastest of the slow....

    the part number for the crank pulley is on the outer face of the curved area between the where the V belt rides and the flange where the pulley bolts to the balancer. Hard to describe, but you should be able to see it easily without removing the pulley. For proper belt alignment, your going to have to match your existing pulley, or find someone whol'll sell you a matched 777/778 set
