Shock Mounts
These are troublesome as they are almost always broken due to deteriorating rubber. Even NOS ones fail if you put a set on them. To fix them (or reproduce them) what I have done in the past is bolt the two bottom angled pieces to a metal plate at the correct horizontal spacing. Then I put a threaded metal rod in the centre with a bolt at the right height to position the central U shaped piece. This rig holds the three pieces in their correct spacing without the rubber. I then welded the pieces together (with a little filler and careful to have the weld within the joints) then filled the spaces with black silicone. Dry, cut the sides and you're ready to go.
