With a 3/8" diameter, you appear to have our Series 400 spiral balances. However, please remeasure their lengths and include only the metal tube portion of the balance, not the tips.

Thank you for the information.
Please take a look at our S400-25 and S400-35 Spiral Balances, for your 25" and 35" balances, respectively. As for the bracket, I think our 17-031 would be your best choice.
