Trying to identify oil pump, part #12556436
Title says it. I have an oil pump marked with part number #12556436
I've searched around and found some posts that suggested this is a 2001+ lsx oil pump (supposedly they are all the same). I've also found posts that suggested the 2001+ oil pump had a different part number, #12586665. So which is it?

12556436 doesn't appear to be the right number (edit: see what Paul Bell says below).
but 12556434 was superceded by 12586665.
