Hello, Your pivot shoe appears to be a match to our 15-177, which is compatible with the S152 coil springs. This assembly is commonly used with the 26-466 but you would need to remove yours from the sash to compare to the style and dimensions shown on our product page. If you need new tilt latches as well, take a look and compare the specifications of the 26-243 and 26-244 to yours. Thank you! Dimensions for 26-466
