Thank you for sharing your information and photo with us. You should be able to go with two of the S152-7 coil springs ( for a 14 pound sash) and or two of the S152-8 coil springs (for a 16 pound sash). It is up to your discretion on which set of coils you want to go with. We also placed a list of coil spring accessories on this page for you to look over. |
