Replaced old top and bottom plates,  intermidiate-mass (IM) stoppers and IM slide guides, and dampimg-mass holder of IMMT2's suspension system to new ones.

(For this work, required to modify the shpae of dampimg-mass holder. Thanks to MESCO Inc. for machining it immediately. )

Assembled the suspension system again, and finished the preparation toward hanging mirror.
