Thanks for posting! This balance assembly appears to use the 15-177 Coil Balance Shoe. I am confident this should be the replacement you need but be sure to compare the specifications.

The compatible coil spring is the 1/2" wide Series 152 Coil Balance, which is attached to the shoe using the 33-072 screw. You'll need to look for a stamp/marking on the metal to determine the correct replacements. If yours does not have any, please review the video tutorial below for instructions on selecting the correct coils.

The covers can be replaced using the 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and 15-145 Coil Support Barrel, which all snap together.
