I am glad that you said something. I have some on the bench ready to be mounted. Your comment makes absolute sense thou. The ring on the hyde style mount locks that sort of movement out. Dave Brown sells a similar style mounting system. It is mounted to the engine backplate and with out stand offs.

Thinking out load now...
If the motor was mounted to a ring similar to the your hyde mounts then the sandwich mount between and to the firewall that would eliminate the translational stresses that the motor standoffs would be subject to. Just a thought.
I know, "just make the hyde mount already" ggeeesh.
Again thanks for saying something.
