Looking to repair windows in an apartment in nyc

Question

I am trying to replace the balances and possibly the whole side track assembly of a number of clad wooden replacement windows

The plastic receiver has a patent number that is a swisco product

Thanks for your assistance

Hello,

Take a look and compare the S770-34 channel balance with a 34E strength option to your assembly. As for the pivot shoe, I'd recommend removing it from the jamb liner to compare to the dimensions shown on the 15-129 product page. Thank you!
