I need to identify what parts I need, please.

Let's start with your balance. Our Series 600 spiral balance should work well as a replacement. If you are looking to replace them, we would need for you to get back to us with the tube length. Since you hardware parts are on the older side, you may also want to consider going with our 75-006 charging tool to help assist in the installation of the new balances. We placed some media guides on this page that shows you how to do that. Moving on to your pivot shoe, take a look at our 15-046. Review our measurements and see if they are compatible with yours. We have known this size pivot shoe to be very popular in the vinyl window business. We also placed some media guides on this page that can help you with your pivot shoe.
