Balance Coil Replacements Needed

I have attached pictures of what coils need replacing in each window. The windows are are vinyl, single sash,double pane windows. Two of them are 22w x 29h and two are 33w x 29h. The Series 140 look like they will do the job for both windows, assuming I get the double coil for the larger window? Do I order left and right coils?

Thanks for your help

Note, in the post with pictures, that the double coils for the 33w x 29h window sash are located at top of window so I assume the coil spring needs to be long enough to reach the lower sash.

The 22w x 29h sash weighs 12 lbs.

The 33w x 29h sash weighs 19 lbs.

Attached is pivot bar picture with dimensions.

In addition to the previous post picture, note that the pivot bar is rectangular in shape: .2 inches high and .3 inches wide.

The larger window 33w x 29h, had the coils mounted at the top for some reason(see picture). This required a coil that is about 54 inches long. Will the S140-10 coils be long enough to work from there, or can I just mount them lower and still have full window operation?

I just wanted to thank Paul for his assistance in determining the correct balance coils for my windows. I installed them without too much trouble today and the windows are operating much better. Your friendly and timely assistance means I will always turn to SWISCO first for any future hardware needs.
