Does anyone know were I can get a two groove water pump pulley? I am putting A/C on my 73 Bronco and I currently have a one groove pulley. I got a three groove one off of a 83 Fairmont but it had a longer water pump shaft and when I put it on my pump it would hit my block. I need one that will line up with the two grooves on my harmonic balancer. Thanks for any help.

They are very tough to find. I ended up having one made out of aluminum stock. This pulley, in the link and plans, spins the H2O pump about 10% faster than stock for better cooling at idle, and has no clearance issues when using a later, larger diameter, double groove harmonic balancer. Original early double pulleys + late double groove harmonic balancers often interfere. If you have room in front (the biggest question), it will be cheaper to use a later long pump, late triple pulley, and late 5 or 6 blade fan.
The plans.
Have the finished pulley hard anodized, or have two made and plan on replacing it every 20-25,000 miles. The belts will wear open the grooves in a raw aluminum pulley.
I had "big plans" to have a bunch made and offer them up a few years ago, but my connections in the "poor, broke, and desperate" machinst word are slim. Use the plans as you wish. If you reproduce a bunch and go into business, making millions, mention my name with kind words.
