Thanks in advance for your help - we are a water pump remanufacturer and I am in search of a good information site that will give me water pump casting numbers so that I can provide original pumps to the restoration industry. We have a lot of old cores but I am unable to determine which casting numbers are in high demand. Any help or suggestions would be greatly appreciated!
