Replacement part for vinyl windows

Thanks for posting. This is a coil balance system. Your old pivot shoe is no longer made, but the 15-177 should replace it. The coil springs are the Series 152. If your old coil housing is undamaged you can reuse yours--otherwise, see the 15-143, 15-144 and 15-145. These pieces 'sandwich' around each individual coil. Let me know if you have any questions.
