Not sure if this is broken or came apart
Thanks for your post! Our 15-087 Coil Housing Pivot is not an exact match for your assembly but I do believe it will work for your repairs. You'll need the 15-086 Tandem Coil Housing to replace the top part of the assembly.
Carefully compare the width and thickness of the 15-087 to your bottom pivot to confirm this will be a fit.
Both of these housings are compatible with the Series 180 Coil Balance. Since your housings are marked with a 7, you'll need the S180-07. These are usually anchored in the window using the 16-024 Mounting Bracket.
The pivot bar can be replaced with either the 26-422, 26-369, or 26-412. You'll need to compare each of them to the existing pivot bars to confirm the correct fit. Each of their dimensions can be found on the website.
