We took a walk-about into the LVEA this morning and confirmed that the systems drawings for the HAM3 and HAM4 chamber feedthroughs (feedthrus, viewports) flange layouts -- D1002874 and D1002875, respectively -- are correct in that the top feedthrus are current not used, and have blanks installed. Pictures attached.
