You are quite right. It looks like you need either the series 380 or Series 385 balances. The difference lies in the shoe. The series 385 balance has the 15-004 shoe which is 1 3/32" deep from front to back. The Series 385 has the 15-005 shoe which is 1" deep. If you measure your shoe you should be able to determine which one you need. Please let me know if you have other questions.
