I just put a Clarks Superdome in my MBW 1665 and had the same issue as JMB. I just used a ring of Hypo and the base of the rehaut placed the crystal on it, but the compression ring was a little loose, so I put a touch of epoxy and 12, 3, 6 & 9 and glued the compression ring down. Anybody see any issues with this? I am sure I can still get everything apart if needed, just wanted to see what the opinions out there might be...seemed a little janky to me, but it did the job and it looks great!
