Mirror parts breakdown?

[97audia4]

Loose rock from a pothole shot up from the car in front of me today and smashed the passenger side lower mirror. No damage to the front piece just lower portion, can I order just lower section and replace?

Looks like the part you broke only comes with the mirror assembly:

But I just replaced the passenger side assembly on our PPV, and it wasn't that terribly expensive.
