The left side has 2 coils stamped #5 and the right side has one coil stamped #8. Here are more photos with measurements.

I understand about being symmetrical on both sides. The windows were installed be the builder about 15 years ago. I checked other windows, and none of them (same sized windows) seem to be consistent with the installed balances. Should I just install a #9 one each side of just replace the shoe for now?
thanks

The window is 17.4 lbs. Will the coils spring open once I take the screw off or will it stay compact? Wondering if I should just change entire assembly on each side. Additionally, the pivot bars are "Z" shaped, can they be changed to straight bars? The "Z" shape extends below the window and interfere with window air conditioners.
