You will need a custom made replacement balance with the 19-002 top and the 15-005 shoe. Take a look at both of those attachments and make sure they match up to your balance attachments.

To receive a quote on this balance fill out our custom balance form. After you fill out the form you will be emailed a quote and an ordering link.

Let me know if you have any questions.
A quick learner says:

I think our 18-009 top sash guide may work. It would be better to look at an unbroken one on a different window to help you decide. You can also take a look through our top sash guide catalog section to see all the other styles we offer.
