72 LT-1 pulley
What is the correct part number for the Water Pump Pulley on a 72 Corvette LT-1 car with power steering and NO A/C ?? This is a 2 groove pulley.

After some cross-referencing it seems like this might be the part number: 3991423
I'd buy that ebay thing before it disappears....even if you're wrong it's under 25 bucks. but here you go.....
