Where did you get that number?
There is nothing in any of my GM parts books or Google.

That's the casting number for the lower pump cover, which was never available separately from Service; pumps were only sold as assemblies. No telling what different pump assemblies used that cover.

Well guys i decided to remove the oil pump gears and measure the height. They are the 1.3 gears that were used on the ZL-1, L-88 oil pumps. So i have the corrrect oil pump for my 6 quart BB Chevy oil pan that was sold over the counter. A 1967 pan that was used on the 67 L-88 Corvette and would fit Camaros. I will install this setup on my 69 Camaro drag car. Thanks Steve, appreciate the help.
