Just to be a little clearer, non A/C cars used roughly a 7" crank pulley and an 8" water pump pulley while A/C cars swapped sizes and had 8" on the bottom and 7" on the top to overdrive the pump and fan. There is about 15-3/4" between centerlines so two 8" pulleys won't work since they hit.
My notes show the following part numbers that I had on my original A/C GTO.
Crank 8” Double Pulley 9786907
Crank Single A/C Pulley 9782704
Water Pump 7” Pulley 9786909 XJ
The Parts Place offers all three reproduction A/C pulleys on ebay. they even have the correct part numbers stamped on them. I've ordered and installed three sets from them for club members' cars and only problem was one water pump pulley had a wobble and had to be replaced. All others looked and performed like original pulleys.
