Does the top fitting have wings, or side tabs, like your bottom nylon fitting does? Or does it lack them? If it has wings, see our S380-28 or S385-28. The only difference between these two balances is the depth of the bottom nylon shoe, or 'heel-to-toe' measurement. The image below depicts the difference. Compare both with your old hardware to determine what you need. For a new stamp option choose 2730.
