These parts are for a 30 year old mobile home. On the picture of the track I believe that there is a little piece of metal that acts like a shelf for the plastic part to catch on some of those little shelf have broken off. On right side the screws are Phillip's screws and on the left side it is just a little round whole. I tried the security bits that I have and could not remove, I could probably drill those out and replace with Phillip's screws.

Hello! Please see our 91-174 Phillips window latch. This looks just like the part in your photo and I think it may be just what you need for this project. Look it over and let me know if you agree.
