My Mastic windows were installed in 2001. Most are in really good shape except for the tilt latches have snapped off in a few. Do you have parts to replace them? It looks as though they just snap in -- no screws.

I am afraid these Mastic Surface Levers and Internal Tilt Latches are no longer made. You might be better off seeing if you can convert to surface mount tilt latches, such as our 26-228 & 26-229 or 26-193 & 26-194. The video below shows how.
