A quick learner from Sanford, NC says:
The counter spring top connector has broken on both sides. I removed and attaching picture of one.
Advise replacement assembly.
Also the plastic tubular seal on the bottom sash to sill needs replacing. Can I purchase lengths?

Thanks for posting. This looks like our Series 850 balance. See if you agree. These balances are sold as complete units, and the individual compontents are not available separately.

I need the bottom sash seal to window sill. Is this available in feet? The measurement is 3/8" dia and has a 3/16" track width to fit the slot on the window base.

Not sure what you have, exactly, but look at our 58-135, 58-182, and 58-183. Do any of these match? If not, I will need to see pictures of your seal's profile in order to find a good match.
