Welcome to SNS ------ and, you may look at "FlowCooler" web site .
I have a 69 Nova with a 250 / 6 ....... with Factory A/C ....... and this
CAR Has an A/C "six - WATER Pump only" --- short style six water pump
with a 7 blade fan with a "fan Clutch". The last water pump that I bought
------ they (the auto parts store) told me they were only 'six left' - rebuilt ones in stock --- quit making any new of this type water pumps.
I've kept all my cores, and checked the Flow-Cooler site just for this info. Might work .... worth a phone call .....
