Broken Coil Window Balance

A quick learner from E. Amherst, NY says:
I have a vinyl double hung, double glass, tilt inward replacement window with broken 1/2 inch coils on each side. I removed each broken coil from each of the tracks and they are both stamped 7FB. There are 2 holes at the top end that were attached with a mounting bracket that looks like part #16-024. I believe I need 2 part #S180-7 coil window balance.

The lower piece of the broken coils are still in the jamb. It looks like the broken coil is encased in a plastic part that might be tandem housing 15-086, based upon your web pictures at: 7-lb/pd/Series-180-Coil-Balance/S180-7

or a part #15-087 coil housing pivot based upon picture at: Pivot-Lock-Coil-Housing/pd/Tilt-Window-Replacement-Pivot-Lock-Shoes/15-087

Whichever one it is, they both look like they are not broken.

I can't figure out how to remove the tilt in sash, so that I can get at the broken coil and replace it. Can you offer some suggestions? I

Sure! The sash should just tilt in and pop out. Check out the video below and see if that helps.
