Hello, thank you for posting,

Please review the 15-087 pivot shoe along with the Series 180 coil springs. Compare the dimensions below to confirm a good fit!

Detail of 15-087

Based on the (6) marked on the pivot housing, you should be able to use (1) S180-6 coil spring on each side of the window. This will give you 12 pounds of support. I recommend removing the sash and placing on a bathroom scale to confirm the weight is correct.

I agree with your assessment of the 26-422 as long as the dimensions match up!

Let me know what you think and if you have any additional questions!
