These are at the bottom of the windows on the right and left side, they screw into the bottom and then go into the guides in the window frame. When they are not present, the windows won't stay up. I need at least 10 of them. As you can see in the second picture, one is the part I need and the other is a broken one. when you slide it into the bottom of the window the phillips head screw holds it in place.
Thanks!
