Balance coil spring

A contractor from Plymouth, Mi says:
Looking for proper replacement springs. I have purchased from you before but only ordered the S152-6 shorter tab coil. I also need the long tab coil.
Thank You!

Thanks for writing in. Can you show us the pivot shoe that these springs attach to? The identity of the pivot shoe determines the identity of the coil springs. Many thanks.

Many thanks for your correspondence. The letter E stands for 5 lbs. coil spring. Unfortunately the coil spring S152-5 only comes in one length. The long tongue on the S152 coil springs was discontinued some time ago. You can still just use two S152-5 coil springs, it will just be a little harder to connect the top spring to the 15-175. Let me know what you think.
