Sho,
These pictures are great. It looks like the Ecal crystals need to be moved to the right by about two crystal widths, or the vac chamber to the left.

Okay, here's some sections of the flange at different values of Z; center of viewer is (0,0) I think - I have no idea what I'm doing but I managed to get SLIC to display the geometry.
Looking at the Z=150 view, it looks like the photon hole is ~15 mm (somewhat more than one crystal width) from the center, where you'd want it to be at (150 cm)*(30 mrad) = 45 mm?
