I will check with Franks. I also saw some on Ebay that are part number 9796134.
Also, I have the 8" diameter water pump pulley that was on the car prior to adding AC. Now according to the chart it calls for a 7 3/16" pulley on the Firebird. It also shows 6 1/2" for other Pontiacs. I can't seem to figure out why one Pontiac V8 would be different than a Firebird or Tempest V8?
Since my temp cools off quickly after the light flow troubles seem to be an issue as well as the fan, shroud and baffles. I have adjusted my shroud and I am in the process of getting the upper and lower baffles. I still haven't decided if I want to pull the water pump and put the cast one on yet.
