|Modular F.R.L.

Is it possible to replace the regulator of an old AC series modular F.R.L. unit (2 digits: AC□□) with a refreshed AR-A, AR-B, or AR-D series regulator? Are they interchangeable?

A refreshed AR□-B series regulator can be mounted on an old AC series modular F.R.L. unit using the original AC series spacer.
Note) AR□-D and AR□□-A series regulators cannot be mounted on old AC series units.
