In building a 350 SBC for my '63 GMC I've run into a problem. There were no pulleys with this engine when I bought it. It needs a 7" dia. pulley for a short water pump with a wide bolt pattern on the flange. So far all the pulleys that I've found are for the narrow bolt pattern flange and the only pulleys that have the wide bolt pattern are for long water pumps.

Can anyone tell me if the pulley that I need has ever been made and where one could be found? Thanks in advance.
