Black object at top of upper window, one side missing

Hello again. The black object is called a top sash guide. We carry a ton of different kinds, which you can see here, but in order to narrow it down I need a clearer picture of your original. Specifically, I'll need you to remove an undamaged version and show me a clear shot of its front an side. Think of it like a mug shot.

The other piece you show is called a sash stop. We don't sell this one, unfortunately.
