Coopman: During the course of mounting my newly-acquired C8 OTA (CG5 dovetail, same as the SE mount uses) on my 6SE mount, I did some experimenting. The bezel is easy to remove (4 screws). The dovetail bar on the C8 then fit fully into the clamping mechanism & the mount worked perfectly. As Dan commented, the bezel is cosmetic & serves no functional purpose.
If you look at photos of nearly all other mounts, no bezel is used: all of the GEM-types, the Ioptron, the Vixens, etc.
In case it has become impossible to obtain an 8" bezel from Celestron (I consider this turn of events disastrous), you can still mate your C8 to a 6SE mount by either removing the 6" bezel, or by placing shims between the dovetail bar & the C8 OTA, as described above. I tried both, & both methods produced excellent GOTO's.
As I stated previously, my shims are available.
