Pivot shoes and hardware for the window
Thanks for your post! The housings with the nylon cams, can be replaced with the 15-087 Coil Housing Pivot. The second assembly also uses the 15-086 Tandem Coil Housing.
They are both compatible with the Series 180 Coil Balance. You'll need to check the stamps/markings on them to determine their replacements. If you do not find any, take a look at the video tutorial for instructions on selecting the correct coils: How to Choose A Coil Balance Weight Option
The pivot bar in the first photo can likely be replaced with the 26-382S Pivot Bar Case and either the 26-083 or 26-089 Pivot Bars. The other one, with the tabs, can possibly be replaced with the 26-247 Upper Sash Pivot Bar.
The dimensions for each of the recommended parts can be viewed directly on the website.
