Window balance

Hello, thank you for posting,

We should be able to assist with a replacement coil balance assembly, but to further review, are you able to show us a picture of the pivot shoe that the coil spring attaches to? The window sash would need to be removed to show access. From there we can determine the best fit for your window. Thank you! 

Thank you for the additional image, 

Please review the style of the Series 140 coil balance as a replacement. Compare the overall dimensions below to confirm a good fit! Based on the 6R stamp, see the S140-06. Let me know if you have any additional questions.
