Broken Window Tilt Part

Hello,
I have a window with broken hardware. On the left side the tab that slides into the wall has completely broken off. On the right side it's just bent. The window has also completely lost its ability to stay up and just falls down, but since it's the top/back section of the window, I've been able to keep it shut with the lock. Are these specific parts available? I'm not even sure what they're called so I'm hoping you guys can help. Thanks!
