Spring load broke

Hello,

It sounds like you're referring to the metal basket shown in your photos, which is actually part of the pivot shoe that the spiral balance attaches to. I'm doubtful that an exact match is available but we may be able to supply a modern replacement for your pivot shoe. To get started, we'll need to see photos of an intact pivot shoe fully removed from the other side or from an identical window in the house. We'll also need you to write out the exact width and thickness of the shoe to narrow down your options. See the videos related on this page to help you through the process. Thank you. 

Thanks for getting back to us but, unfortunately, we are not able to make out exact dimensions from photos. We'll need you to write out the width and thickness of your pivot shoe to compare to our inventory.
