A/C crank pulley part numbers
 

I need to order pulleys for a small block with air. Does anyone have the part numbers for the crank pulleys. I think that there was two stacking pulleys. I'm not sure if it is suppose to be a single then a double or a double then a single. I hope someone can help with these numbers. Thanks

71 AC pullies for sbc, short water pump setup. Pullies are both stamped metal. Double pulley next to damper, PN 3744043BA

Single outside pulley that nests into the double pully, PN 3751232.

Earlier cast pulley setups have different spacing.

water pump puley number, does anyone have the part number. When I bought an a/c belt from gm for this application it was to long. I'm wodering if I have the correct water pump pulley. I have the same crank pulleys as numbers above.

Here is the water pump pully number that I have:

PN 1235778

It is a double stacker.
