These here are orginal water pumps with casting # 9772716 used on the 1964 and 1965 years, these pumps have been rebuild, repainted, and come with the gasket. Look at the different photo's you will notice one has the casting #716 on top and the other with the casting #716 on the bottom of the pump, both loctions are correct. If you are doing a Concours frame off or just a daily driver and want to be 100% on the water pump this is it. Even if you can find a used core for $75 and that's a big if and have it rebuild for $100 you are at $175. I HAVE A LIMITED NUMBER OF THESE PUMPS
