    This is a winner. Losing the strut is no big deal since the ability
    to fine tune engine pitch is retained.

       People who are new to this list would be amazed at the five year
    history of the evolution this design.  Paul has probably drawn a
    hundred iterations. Over time,  the engine mount got better, slowly,
    but it has not been easy.  This mount is light, incredibly strong,
    and it is OUT OF THE WAY of other engine components like the exhaust
    system.  This engine mount was engineered by Paul, without
    compromise. Even though I have asked him on many occasions to fudge
    just a little, to make things easier, most of the time  he did not
    seem to hear. Other times when he definitely did hear, I received a
    smoking e-mail setting down the law.

       This engine mount is designed  to provide space to put the radiator
    under the engine with a properly shaped intake plenum.  To do that,
    the oil pan had be redesigned and it has become a functional part of
    the engine mount both because it is the anchor for the rear beam and
    because of its shape.   Anyone can just buy the engine mount and get
    on with his conversion.  No big deal now, but to those of us who have
    had a part in bringing it to where it is today,  this last iteration
    is MAJOR.

    Paul,  if you have time, in the attached drawing change the center
    section to 6.5 inches as we discussed and also indicate the angle
    between the arms and the center piece.  I want to start building the
    fixture for this piece tomorrow.      Thanks,  Jerry

Thanks,

MORE VIEWS???? :) What perspective did you have in mind Matt?

Here are some shots of Bob Whites earlier version.

We did not need the P51 style side beams then but they were key
to implementing the new design with the rear MM beam.
