Coils needed for ELITE double hung window

The coil mechanism for the upper section of the ELITE double-hung 33" wide by 68" high window fell apart. I was able to remove the other one (see attached photos). I checked all 3 coils for additional information. They only show stamped numbers - top 5, middle - 5 and bottom - 6. I was told that these indicate their capacity in pounds so the total value seems to be 16 lb.
Additional information provided on the attached sketch.
Would you have something that can replace these coils? I think I will have to replace them on both for sides for proper balance.

Thanks.

Paul, thank you for your reply and apologies for the delay in my response. I had to wait for the window company to come and replace the glass in this window to be able to take the photos of the metal pin that you mentioned. Please let me know if the S140-16 model would still work with this pin in place.

Thanks.
