Double-hung window tilt-out clip

I rent an apartment where there are a number of double-hung aluminum windows that were installed in the 1970s, according to the property manager. On several windows, one or both of the clips that allow the lower pane of the window to be tilted into the apartment from the inside for cleaning have broken. This results in a slightly draftier apartment at times, and where both clips are broken, the lower pane sometimes falls into the apartment. I'm looking for the clip assembly. It is spring-loaded. Some of the broken clips are on the left side, and some are on the right. Replacing the clips appears to require a small amount of windows disassembly (removing the top portion of the frame). I'd be interested in ordering perhaps five of each of the left and right varieties.

I'm happy to provide more information if you can tell me what you need. It's an odd piece to try to describe or measure.

Thank you,

That's it! Thank you.
