Paul - I think here's a possibility maybe worth considering on revising your engine mounts. Perhaps use these
insert mounts bolted to your existing black bracket (3 point bolt side). You will then need to reconfigure your frame stand piece to step the mount face back enough to fit the mount between the two fixed brackets.
The frame side plate would be setup for a single bolt/washer connection that goes up through the underside of the plate into the flexible mount center threaded insert. The insert mounts become your front of engine vibration dampers. Make sense?
