Hello, I would recommend removing your coil balance hardware from the window to compare to the specifications of the 15-199 pivot shoe, which uses either the Series 160 or Series 165 coils depending on the width of your original springs. Once you determine the correct coils, there should be numbers stamped on the coils that will tell you the corresponding strength options for your replacements. Thanks for posting! |
