Need to replace spiral balance and correpsonding pivot shoe. Balance is 29 inches long and approx. 3/8 diameter. Seems to have a white or very light green tip. Pivot measures 1/2 inch thick, 1-1/8 inch wide, and 2 inches long. See attached photos of old balance and pivot shoe. Need help choosing correct replacement parts.

Looks like you have the S900-29 balance. See if you agree. Now, while the S900 balances normally take our 15-045 shoe, I'm not sure if that's what you have. See our 15-046 shoe instead, since it's a little larger. You will have to remove yours from the window frame to get a good measurement, then compare that to our hardware to confirm whether it will work.
