Question

Our windows are 20 years old, and when I tried to clean them they break off. I use WD-40 to help but I don't know if I need the whole side with the springs. I sent The message on the window if that might help

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.
