Pivot pins and shoe
Hello,
Your assembly uses the 15-177 Coil Balance Shoe, which is compatible with the Series 152 Coil Balance; secured to the shoe using the 33-072 screw. Take a look at the video tutorial below for an explanation on how to determine the exact coils needed for each of your assemblies.
The 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and 15-145 Coil Support Barrel can be used to replace the cover/support.
I'll need to see an undamaged photo of the pivot bar to determine the best replacement match. There are quite a few that have a similar tip. Both of these appear to have a different hole spacing.
Feel free to reach out with any other questions you might have.
