All rep and gen Rolex GMT ceramic inserts should be close enough in inner and outer diameters to be interchangeable - approx 30.8mm / 38.0mm. I've never come across one I couldn't swap. Once I had to sand a tiny bit off the inner perimeter of a rep bezel rim to fully seat a replacement ceramic insert. Sometimes a difference in thickness can be an issue and some improvising is necessary like adding an extra tape ring, spacers or a glue bed. Or in some instances, thinning the replacement insert.

It's also pretty common among similar production era reps that bezels can be swapped around. The chances for a successful swap increase if the bezel's matching crystal retaining ring and other bezel assembly parts are included. The case rehaut then becomes the determining factor, and most of those are going to be very close in outside diameter since they all have to fit a gen-spec 29.5mm crystal.
