My windows have 15-177 balance shoes and 26-466 pivot bars. Unsure of the coil weight. Windows are vinyl. Lower sash is 32" x 38". Thank you

Hello,
The 15-177 pivot shoe uses the S152 coil springs. There should be numbers stamped on your original springs that you'll need to choose the corresponding strength options. If not, you would need to weigh the sash and divide the weight by the number of coil springs used on each side. Thank you!
