Hi guys, just wondering what the right part number is for the original water pump pulley, on a 73. I'm not sure where mine got to while the motor was out.

I found a few, by searching for oldsmobile 455 water pump pulley, the first looks like the best deal:

1. https://www.ebay.com/itm/166385557336 (lists: GM pns 399404 and 409807, stamped codes KK, KF, KO, and KN)

2. https://www.inlinetube.com/products/inl14688 (stamped code KK, looks same as 3 and 4)

3. https://www.oldsparts.com/product/water-pump-pulley-ac-1968-73-cutlass442-3-groove-water-pump-pulley-with-ac-fits-all-350-400-455-motors-and-w30-w31-h urst-olds-has-3-grooves-with-a-5-34-diameter-sold-individually/

4. https://www.opgi.com/engines-components/belts-pulleys/1968-72-3-groove-water-pump-pulley/pulley-water-pump-1968-72-cutlass-3-groove-code-kk-c241594.ht ml

I did not answer when you originally posted this because I would just be guessing but it looks like any of those 3 groove pulleys would work.
