Need L83 water pump part number

[SilverDriveR2024]

Hi guys! Is there any efficient way to find the number part for the water pump on my L83? I have been trying to find the number in the last few days but without any results. Can you help me?

If I'm not mistaken, it's ACD 251-796.

Oh, wow! GM Parts website lists the part as GM Part # 19382527. The number you gave me is totally different. I don't get it. Thanks!
