Thanks for posting. This looks like a 15-087 Coil Balance Shoe and 15-086 Tandem Assembly. Once you remove your assembly from the jamb track, please compare with the diagrams below to ensure these parts match what you have. You can do this using our 75-069 Jamb Spreaders, but you also could remove the shoes forming a cutout in the jamb track. The video below shows how to do this for a different coil balance system, though the principles will generally be the same.
