Thank you for sharing your photos with us. For your pivot shoe, our 15-192 looks like a good match. Take a look and let us know if you agree. If you are also looking to replace your pivot bar, you will need to remove it completely from the window and upload a photo for us to see. You will also need to include some measurements.
