Pivot lock shoe

Many thanks for your post. We believe you have the prime window pivot shoe. This connects  with a channel balance that uses a hook like the 15-036  to connect to the shoe. Please confirm. The replacement shoes are designed as such so you don't have to make a cut out to install. See the 15-106 left hand shoe and 15-107 right hand shoe. You can reuse your metal center cam and the brake shoe (the 15-054) if they are undamaged. Let us know if you have further inquiries.
