I'm looking for a water pump pulley for my '86 Camaro 2.8L V6. I do not have a part number unfortunately.
I'm adding factory air to the car and the present pulley has 1 serpentine groove and only 1 V-belt groove.
I need the one that has the same serpentine groove but with 2 V-belt grooves.

Picture for reference to what I'm looking for. TIA!
