left and right side spring replacement

Question

I have included the pictures of the current window balance spring and shoe. I need both the left and right side replacement springs for this window. The spring number is 6JK, so 6 pound springs? Attached is the window size.
Thank you,
Kevin

Hello,

We can't be sure with your hardware still installed, but your housing pivot resembles the 15-087 Pivot Shoe, which works with Series 180 Coil Balance springs. We offer the 15-086 tandem housing and 16-024 mounting bracket as well. Review the specifications to confirm they match yours. Thanks for posting!
