Broken Coil

Hello.....first of all, thank you in advance for your support. I'm having trouble finding a replacement for my mom's window. The only "Code" stamped on the coil is the letter "D". I'd like to replace both left and right side.

Again, I appreciate your help.
Have a wonderful day.

Hey Frank. The pivot shoe looks like our 15-177. Just make sure the dimensions below match up. This shoe works with Series 152 Coil Balances. A coil spring stamped 'D' should translate to 4, for the S152-4 4 pound spring. If your old coil housing is undamaged you can reuse it; otherwise, see our 15-143, 15-144, and 15-145. These newer style components 'sandwich' around each coil. Let me know if you have any questions.
