Do you have my spiral balances?

A handy person from New Jersey says:
Need several of these. Both left and right. Our windows were installed at least 15 years ago by BEST windows here in New Jersey. I;ve also ordered 10 sets of Tilt Window latches.

Thanks for posting! Looks like these are actually coil balances, not spiral. It's hard to tell what exactly you have based on these images, but could your pivot shoe be our 15-087? Carefully compare the two and let me know. If so, then you might be looking at our Series 180 coil spring.
