Hello! It looks like your pivot shoe is broken.
We sell the 15-192, which is very similar to your original. This very well may work for you but there are two important details to note:
- We only sell the newer version of this shoe, which is designed to have a slight protrusion, or bump, on the face. Past customers have told me that these bumps get in the way of installation in older windows and, as a result, they had to cut them off or shave them down. That's something you may need to be prepared for.
- The new style metal cam will not be compatible with your original pivot bars. That means you will have to reuse the old metal cams; they can slip in and out of the plastic housing.
I hope this information helps. Look over the 15-192 and let me know if these qualifications are acceptable.
