Need to replace this plastic window part

Question

I have very old windows. This white plastic part broke and now the window cannot stay open. Do you happen to have a replacement part that may work with my window type?

Hello, thank you for posting,

It appears that these parts are a broken balance shoe and a possibly a part from the top sash guide. I have related videos on the page for more information.

To move forward, we will need to see an undamaged balance removed from the window where we can see the top and bottom attachments along with an undamaged top sash guide where we can see a face view. From there we can get a clearer idea of replacement options for your window. Thank you!
