Well, it used to be
LS1/LS6 water pump (98-02) (AC-Delco #252-781) = 12458934

I thought I had found the updated number to be 89017456 (AC-Delco #251-690), but on looking that up, it says it's only used for the LS2 GTOs, and 12458934 is still supposed to be used for LS1s!

You could just do a Google search for the old number and buy it from the company still selling it under that number, which comes up towards the bottom of the first page of results.

Interesting, that part number maps back to the same AC-Delco #251-690 too. However, Pace finally confirms that it is the new one for LS1/LS6 in addition to being for LS2!

a gm one will be better a little, but the autozone one will/should be fine. normally gm stuff is new, and the parts store stuff is normally reman stuff.
