I assume what I have is similar (or even identical) to your P/N 26-334. Your pictures on https://www.swisco.com/Top-Tilt-Latch-Set/pd/Internal-Latches-For-Tilt-Windows/26-334 lack the bottom view. Could you send me bottom view picture. Thanks.

Your internal latch is actually a different kind that I am afraid was discontinued some time ago, and is no longer available. Instead, consider seeing if you could convert to surface-mount tilt latches like our 26-193 & 26-194 or 26-228 & 26-229. The video below shows how to do this.
