I believe it is called a certain teed pivot bar. The number on it is 103-2. The pictures I've attached show it broken. I need to replace it. I've ordered one in the past but it was the wrong piece.

Thanks for posting! I believe you have the old Certainteed tilt bars. They looked somewhat like our 26-353, but came in left and right. We don't have these old pivot bars anymore since they have been replaced with the newer 26-175. Most times the 26-175 will fit into the old Certainteed pivot shoes, but if not, you will also need 15-192 tilt shoe. Review this hardware and let me know what you think!
