Is there a more narrow version of the S140-13?

I'm afraid that they don't make a skinnier version of the Series 140 coil balance. Are you sure this is what you have? A lot of people purchase our Series 140 since it's a complete coil balance set, but the truth is this is only meant to replace identical hardware. If your original pivot shoe and coil system differed even slightly then there's a good chance the Series 140 won't work for you.

The most common coil balance systems are sold part by part, not as sets. 

If your old hardware does differ, then we'll need photos of your pivot shoe and coil springs in order to ID a better match.
