Thanks for reaching out. These appear to be a dual jamb liner spring but there is a possibility that we may be able to offer a replacement for this part. To start, may I please see a photo of the pivot bar that goes in the pivot shoe?

I can't make any guarantees that we can offer a replacement but we'd be happy to take a look.
