Replacement balance for tilt single hung window

A quick learner from Virginia says:
I have a window that is about 12 years old and both of the balances have failed. In the photos, shown is what I have left of the balances which were for a tilt single hung window.

This balance is a block and tackle design with a screw mount option. The overall length of the rod is 28.5 inches and the base is 1 inch by 1/2 inch.

The photo shows the center plastic parts broken on both balances.

I am looking for the replacement parts or replacement balances to put back into the window.

Good morning! Thanks for posting. This balance appears similar to our S850-28. Does that look about right? I would also recommend the White 1-1/4" Shoe as your option.
