Window pivot bar replacements

Thanks for posting with photos. We believe you have the old Silverline vinyl windows. We offer the 26-330 pivot bar housing for their bottom sash. Compare yours with ours to see if they match up. as for your pivot bar, look to see if our 26-400 will work. We are not really 100% certain because the one we see in your photo is broken. So we'd like for you to recommend our pivot bar to one of yours that is not damaged to confirm whether or not this will work.
