WIndow parts

Question

We have two types of windows in the house, the horizontal up/down kind clearly labeled as Milgard and the push out windows with funky screens. None of these are labeled so I don't even know if they are Milgard windows, though all are likely the original windows when the house was built in 1992. I am looking for the plastic piece which the latches push in to latch the window. Most of these are broken off. I have attached pictures of the window, the latch and the plastic part.

Looks like you need a keeper, but I'm afraid we don't have anything like this. Do you have an undamaged version I can see? That might help me figure out what this is and what can be used to replace it.
