Thanks for posting! Your coil balance housing reminds me of our 15-087 Coil Housing Pivot. The housing attached to the top is the 15-086 Tandem Coil Housing.
Carefully review and compare the dimensions to those shown below to determine if these are the correct replacements. I am confident these are the replacements you'll need.
These coil housings are used along with the Series 180 Coil Balance. Since your housings are stamped with a 5 and a 6, you'll need the S180-5 and the S180-6 coil springs. The plastic mounting bracket is the 16-031 Clear Mounting Bracket.
You may also need the 33-072 #8 x 3/8" SS Pan Head Philips Screw.
