need parts

Hello, Frank. The part in your photo is called a pivot shoe. We sell a ton of these, so I'm confident that we can help, but I will need more information from you before I recommend a match. Please remove the existing shoe from the window and measure its width and thickness. Then, write out what you get for me to review.

You also mentioned an expansion track tool. I believe you're talking about jamb spreaders. If so, see our 75-069.
