Spiral Balance and Pivot-Lock Shoe

Question

I am attempting to replace the spiral balances and pivot shoes in my circa 1990 vinyl windows.

I bought the wrong length spiral balances under the assumption that the upper and lower sashes use the same model. What length is the spiral balance in the photo? I am measuring from the very end of the top.

I cannot seem to find a pivot shoe with comparable dimensions anywhere. I have tried a 5/8" x 1-1/4" shoe, similar to 15-154, but it is a very loose fit. In addition to the images of the pivot shoe, I included a sketch of it with the caliper measured dimensions. Any help will be appreciated.

Hello,

Unfortunately, the company that made your balance system went out of business in the late 90s. With that being said, our 5/8" diameter S600-21 blue tip spiral balance should work as a replacement.

As for the pivot shoe, I would like to see the original installed in the window track and write-out the exact depth of the track to confirm if we could supply a possible replacement. Thank you.
