Parts for a 30-year old spring system (no pulley)

Question

Hi,
I cannot identify the brand, model, or part number and now have a couple windows where one of the mechanisms is broken. The broken piece is the lower end fragmented plastic piece, which connected to the double-hung window.

The window is from a 1987 Kennedy Builders house here in Illinois. Some clues indicate it might be from the Hurd window company.

Do you have these parts? Many thanks.
Andy

Unfortunately, we do not sell the hardware you need. You require new jamb liners, which we don't sell. Is this for a wood window? If so, I recommend contacting a local mill work.
