I would like to replace the balances on both sides of this window with new parts, but I want to make sure I have everything I need and the correct parts.

Hey there,

Thanks for reaching out! We can recommend a replacement for this coil assembly but I'll need to see a photo of the cam on the bottom assembly to identify it. To obtain this photo, you'll need to remove the window sash.

Please let me know if you have any questions.

Thanks for the requested photo. Your coil assembly can likely be replaced with the S161-07. You'll need the 15-086 tandem housing and S180-07 coil spring for the top part of the assembly.

The bracket anchoring the coils to the window track is the 16-030 Clear Bracket.
