I see. I did something
similar on my C11 but I'm thinking, in future, to have the whole baffle tube moving instead of the mirror support.
PS: Looking at the original mirror mounting, it looks like they've used
some kind of white cement. You can see the cork sticks embedded in it. My C11 had three paddle pop sticks. That's for support and initial spacing until the cement cures. I'm really interested in that compound they use. In my experience silicon is the worst thing you can put on a mirror mounting.
