2830 window balance from the late 70's

Question

I can't find a window balance that has a flat top and a bottom without wings. This is an older window so I'm hoping I can find the right window balance.

Hello! Your balance looks like a good match for our S370-29. I think this may be what you need, but look it over and see what you think.
