    Water Pump pulley '67 L79 w. A/C

    Hi. I'm trying to figure out if I have the correct water pump pulley for my 67 327/350 with air cond and power steering. The pulley I've got is a twin-groove with a diameter of 6.25 inches, but someone told me it should be the GM #3770245, which has a diameter of 7 1/8 inches. The one I've got does not have a part number on it. There seem to be so many different pulleys. Is mine a replacement?

    Also, is there supposed to be a reinforcement under this pulley on this vehicle?

    thanks in advance!
