latch actuator part needed

I have a 2"x7/8 inch finger release Nylon window sash release lever that I need.  it's 2"x7/8" with two legs going into the top of the window.  The legs are about 1/4" wide and they have a 5/16 depth.  I need at least 30 of them for an apartment building that I just purchased.  There is nothing in the windows as far as make/model but they are made in 2015, we know this much. I've also enclosed a picture of the window and just above the air conditioner you can see the one tab on the window, it sits on top of the window and moves the spring inside to release the window for cleaning. Unfortunately the picture only shows one leg as the other one is broken off.
