Hello, thank you for posting,

Please start by reviewing the 15-177 pivot shoe that is compatible with the Series 152 coil springs to see how they compare to your original.

It would be best to view an undamaged version of the pivot bar, but start by taking a look and comparing the 26-226 to your original. Let us know what you think and if you have any additional questions!
