Will This Fit?

Thanks for posting. You're on the right track for both balances. In either case, the only other possibility is the Series 380. The lone difference between the Series 385 and Series 380 is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both with your old hardware to see what matches best.

Comparison of the S380 and S385 balance shoes.

Therefore, you'll need either the S380-15 or S385-15, with a stamp option of 1420; and then either the S380-27 or S385-27, with a 2630 option. Let me know if you have any other questions.
