I need to replace several channel balances that appear to be series 390 (S390-24) and are stamped with "2020". Would that have to be a special order?

A Series 390 channel balance stamped with 2020 will have a balance length of 21 inches, not 24 inches. Measure the length of the balance and do not include the fittings in this measurement.
