Power steering pump

[BigTommy83]

I’m looking to replace my power steering pump but it’s asking me for a ZM stamped pump or non ZM stamp. Does anyone know where this stamp would be or if I can tell a difference. It’s pretty rusty, so I’m not sure if I’d even be able to see a stamp, once I knew where to look

i'm not sure what the ZM is for but the GM#20756710. if your going aftermarket provide them with that # so they can cross it over.

gm#20756710 $263.68 walk in price @ dealer.

VIN# cam back as a 99 nbs silverado is that correct
