Hello, thank you for posting,

Please review the 15-252 Inverted Universal Dual Support as a potential replacement option that is compatible with the Series 160 coil springs. Since your original cover is marked with an (11), that should indicate that the assembly holds 11 pounds of weight. You can use (2) S160-5 coil springs for the pivot shoe. Together with the assembly on the other side of the window, the coils can support a 22 pound sash weight. We recommend obtaining the weight of the sash to confirm this. 

Please review all dimensions to confirm a good fit and let us know if you have any additional questions.
