Window Tilt Latch

I need to purchase replacement window tilt latches. To me, these latches appear to have very similar dimensions to your product code 26-420, except that the top part of the latch is rounded instead of rectangular. I believe the window manufacturer is Comfort World which is printed on the window lock. Also, the window has the sticker shown in one of the attached photos. Please help me find replacement tilt latches, as the tabs are broken on many windows! Thanks!

I have the exact same problem and that is the exact latch I am looking for. So did the 26-371 latch work?
