Hi Jerry, thank you for posting, Your pivot shoe resembles the 15-177 that is compatible with the Series 152 coil springs. Please review the dimensions below to confirm a good fit! For a 16 pound window, you can use (1) S152-8 coil spring on both sides of the window sash. For a 13 pound sash, you can use (1) S152-7 on both sides. For a new cover if needed, see the 15-143 bushing, 15-144 bushing cap and 15-145 support barrel. Let us know what you think and if you have any additional questions! |
