Champion windows (Toledo OH) installed 2005. Coil balance springs broken.

Question

Hi! I need to replace the coil balance springs on 3 2005 installed Champion windows. I'm really only not sure about the upper spring supports. They have A-F vertically next to 6 dimples. One has a 3 to the left of the A-F and one a 2 to the left of the A-F.
I'm thinking a 15-150 1/2" standard support could replace those.
I believe the 15-177 can replace the coil shoe.
The sash weighs 18 lbs, so I believe 2, Series 152 9 lbs coils can then be used on the sash. One on each side.
I'm thinking the upper spring supports are not a dual spring type support. I have not removed those to see exactly what they look like inside. I'm hoping you are familiar with those specific parts.
Just need help confirming which replacements would work here. Thank you!

Hello,

Thanks for posting! It does appear that the coil shoe and the coils springs you've selected would be the correct replacements. To replace the cover for this coil assembly, you'll need the 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and the 15-145 Coil Support Barrel.

The 15-150S is compatible with a different coil assembly.
