I can't figure what type of parts will fix my sliding window, and I do not know the barnd

Hi there!

It appears you have CertainTeed brand hardware. Take a look at the 15-192 pivot shoe which uses the S170 & S171 coil springs. The catch is that you'll need to shave down the face of the 15-192 for it to fit into the track. Your pivot bar shown here was discontinued but the 26-175 was designed to replace it. See the video below for more information. Look these parts over and let me know if you have any questions.
