Broken white window block

Question

Hello! I inadvertently broke this piece on my window and I have no idea what's it's called or what to replace it with in order to have my window functioning properly once again. Grateful in advance for any assistance!! One picture depicts the intact part, the other is the broken part.

Good morning! This part is called a pivot shoe. Yours in particular looks like our 15-180. I'm actually very confident this is the part you want. Look it over and let me know if you had any questions.
