Drivers Side Door trim

Good morning all --

I'm looking for some part numbers or names or some other info...

I have a silver Equinox with damaged door-ding panels on the side. The problem is, they're not called door ding panels, so I can't seem to find them by searching.

Could someone please guide me towards what I am looking for, either by part number, name, anything?

Thank you much...

(Oh, and if anyone also has a favorite source for parts too... I'd love it.)
