What is the difference between casting numbers 488296 and 9799124 for a 70 water pump?
I believe they are both the long 4 1/2 inch pump for 1970.

build date of car is first week of April 1970. engine manufacture is March.
I need to purchase a pump for a restoration. Pumps I am finding are both casting numbers.
Which one do I want?
Thanks
