Need help finding a replacement for this window balancer

I am attaching pictures of both sides, where one seems to be broken and the other one seems to be "okay".
Thank you!



Hello, thank you for posting,
It appears that your window uses the the 15-180 coil balance shoe along with the Series 190 coil springs. Please review the dimensions below to confirm a good fit!

The coil spring should have a number stamped into the metal that will indicate the weighted option needed to support the window sash. If there are no markings present, please provide the weight of the sash to move forward.
Also see the 15-182 balance bushing and the 15-186 balance clip if needed. Let us know if you have any questions!

Thank you for providing by the info! I will confirm the dimensions later today.
Meanwhile, I did not quite understand where I would need the balance bushing and coil balance clip. Sorry, I have zero knowledge on this area.



No worries!
In the picture below I highlighted the balance clip in your window. It doesn't look broken so you may not need to replace it.
The balance spring sits under this clip and the support barrel is placed within the coil spring. It appears that the coil has come unattached from the clip in your window.
I have related a video below of an example of how coil balances install/function. Keep in mind that your style is different that what is shown but a similar process. Instead of the coil spring hooking into the shoe, it screws onto the side. Let me know if you have any additional questions! Here to help.
