Tall 488296 casting numbers and the small 72 cast on a K191 pump (November 19, 1971). That's from an original 72 cars with a November 26 production date.
I need to look at my 72 GTO (Oct 26th) and see what pump I have on that car
I always thought the 488296 pump with the 72 casting are the correct one for 72 cars.
