Hi! It sounds like you've correctly identified your balance as an S385-27, if the information you gave is accurate. There's one thing to check, however:
Comparison of 15-004 and 15-005
Comparison of 15-004 and 15-005

The S385 has a 15-004 shoe, which measures 1-3/32" heel-to-toe. The S380 uses the 15-005, which measures 1" heel-to-toe. Measure your old shoe as shown to determine which shoe, and thus which Series, you need.

Based on your stamp, you will need a 2640 stamp option on the new balance. Let me know if you need any more info.
