       I did, however, wonder if anyone had thought of
trying to locate or fabricate a bonded rubber mount.
I have seen rubber blocks bonded between two pieces
of steel used in heavy truck suspensions and in smaller
trailer suspension systems.  After many years the rubber
often becomes badly checked but I have never seen one
actually come apart.  Could something like this be used in
place of your rubber ball joints with bolt arrangement? I am
thinking that you could make the piece the length of the motor
and thus quite thin then you could attach at any points along
 the length of the mount as required. Perhaps it could be
made to replace one of the tubes in your mount?
 I will allow as how the weight could be an issue.
  Hope I have made  this message

The thought scares me. I like to have cold hard steel holding my engine
in there in case the rubber fails. Losing an engine in flight is sure
to kill you. I use the term "rubber ball joint" loosely. What I mean in most
cases is your typical aircraft motor mount bushings like these from
Barry Controls.
