Need replacement of channel balance and possibly supporting parts

Hi Team,
I have a series of windows needing balance repair. They are all similar hardware and I am focusing on one to determine the right parts needed. They are all double hung wooden non-tilt compression sash windows. I was able to remove the balance from the compression sash and can see that the pulley mechanism has failed. It split where it would connect to the spring. The balance has a rib (not just 90 degree angles) and is stamped with what appears to be 22XHD B.S.I. It is 5/8 inch wide and 23 & 1.2 inch in length. I am attaching pictures as well. Let me know if you need more information or can help guide me to a replacement part.
Thank you,
Doug
