I believe your balance shoe can be replaced with the 17/32" thick 15-199 Coil Balance Shoe. To confirm that this is the correct match, take a look over the dimensions.

The 26-378 is the most commonly used pivot bar for this shoe.

Your coil balance support reminds me of the 15-150D Coil Double Support. This is compatible with the 1/2" wide Series 160 Coil Balance. Double check the width of your coil to determine if this is the series you need.

To choose the coil weight option, you'll need to look for a stamp/marking on the coils. If there are none, are they're hard to read, please see the tutorial below. We show a different assembly but the steps are practically the same.
