What are those flip out windows on old toyota trucks in the front called,

[Brian B]

and how do you replace them? Most of the old toyotas actually don't have them. You press a button and they spin outward so you can actually direct air inside the truck at different angles. I need to replace one of them, and I have no money >< I do have access to some glass and someone who could cut it for me for free though.

 

[Mr. Roboto]

They are vent windows.
