2nd HXDS received from LLO

Yesterday I picked up the shipment from LLO contain the 2nd HXDS (first HXDS shipment alog87998) and related ASSEYs and brought it to the Triples lab. 

Uwrapping and inspecting was uneventful, the zip ties were intact, the shock pads untripped and the humidity indicator was unchanged in color. The outer (front, back) and inner (front, back) bags were in good condition, unwrapping the suspension I found no play with the blades.  All the nuts and dowel pins were tight and well seated, the ICS looks good except for it seems to be missing the HDS Intermediate Mass Fixture (D2000230-V1, s/n 08). The part is scribed as V1, on the dcc there's a V2 with two added 8-32 helicoils taps that, based on D1900352 which uses V2, I should be able to see from the front and I don't, so this is a V1 plate and not an incorrectly scribed V2. I believe these two missing 8-32 holes are where we will attach the BOSEM Mounting plate (D2000257). The first HXDS we received in November had the V2 plate. We may have to do a small rework to update it to V2, or have LLO send the V2 part if possible.
