Sorry, Linz, didn't mean to crash the party. Just thought that the config of the guide/bezel, ie not having a slit in it to slide over an installed belt, would be the reason that it wasn't available as a separate spare. Now why they didn't make one with a slit in it, like the Ranger one you linked, is another issue.

Depending on the construction of the guide/bezel and how it affixes in place, you may not have to refix the slit; the guide/bezel may stay reasonably sound as is, especially, as you say, if you place it under the belt so that it can't be seen anyway.
