Thanks for reaching out to us! The pivot shoe you have reminds me of the 15-111 Pivot Shoe. I'm confident this is a match but be sure to double check and compare the specifications.
This shoe uses the Series 160 Coil Balance. Since your assemblies only use one coil, you'll need the 15-150S to replace the support.
To determine the correct coil, you'll need to look for a stamp/marking on one of the existing coils. If yours does not have one, or they are hard to read, please see the tutorial (tagged below) with instructions on selecting the correct coil weight option.
The latches can most likely be replaced with the 26-243A and 26-244A.
The specifications for these parts can be viewed on the website.
