Mark,
I would imagine that the original impellers might have been replaced throughout the years with the GM rebuild kits, so I would have no idea what the original casting numbers would be. I would be more concerned that the impellers are the right length and height and not worry that much about the casting number. Once the pump is installed no one will ever see the casting number. I know the original GM rebuild kits, that are still out there on ebay, come with a new cast impeller and I am sure the casting number won't match the pump it is going on because these kits were made to fit a lot of different pumps. The vanes on my pump are right at 5/8" tall when measured towards the center. They are a little shorter on the outside edge. I still think you got a great buy on your pump.
