Today Gerardo and I removed the unused HAM ISI Oplev viewports from the VP7 ports of both the -X input manifold and the +Y output manifold.  The ports were blanked off with 10" CF blanks.  I noted a series of 3 scratches on the angled flat of the flange, but the knife edge itself wasn't noticeably deformed.  See pics.  

Note to VAC: These will need to be leak checked during pumpdown.
