Need Help Identifying parts for replacement

Hi Paul, thank you for posting,

Your coil assembly resembles the 17/32" thick 15-199 pivot shoe that is compatible with the 3/8" thick Series 165 or the Series 160 1/2" thick coil springs. Please compare all dimensions to confirm a good fit!

Alternate view of 15-199

The original coils should have a number imprinted into the metal that indicates the weighted option needed for each spring. If no markings are present, please provide the weight of the window sash to move forward. The sash will need to be removed and placed on a scale. 

For the pivot bar, please review the style and dimensions of the 26-378 to see how it compares to your original. Let us know what you think and if you have any additional questions.
