Looking for window tilt lock for Milgard Window

From your photos, I think our 26-243 and 26-244 top tilt latches can be used as a replacements. Don't be concerned about the difference in design. I believe they can still work, as long as the measurements are the same. Compare the length, 2-5/8", width, 11/16" and height, 3/8" to yours.
