The metal horseshoe piece that receives the window post is broken. The spring seems fine and I believe it can be reused, but I need a replacement for the pivot shoe. Also I included a photo of the sticker inside the window if that is helpful.

Hi there!
Your pivot shoe resembles our 15-177 which uses the Series 152 coil springs. Compare our dimensions to yours and see how they match up.
