Notes and Changes:

The beam heights from the ground were corrected based on a tape measurement at LHO. Additionally the hole locations are slightly shifted to avoid interference with the existing screws on the panels. The dimension of the flanges were also updated: the inner diameter = 10" and outer diameter = 13".
