66 GTO water pump pulley
 
Finding a profusion of confusing and often conflicting info on what is correct for certain applications. My car is 1966 GTO with Tripower, 4 speed, power steering, air conditioning. What is the correct water pump pulley for this combo? What is the diameter? What is the part number? Info on line states 7 inch and also 8 inch with various part number. Somebody must know the definitive answer. Appreciate any assistance on this.
