Here is some good evidence that we will not be able to use the flywheel in
place of the flex plate.
On this page at Mazdatrix, scroll down until you see the tools labeled
"flywheel stopper"
http://www.mazdatrix.com/ftools.htm
Note that one of them fits the non-turbo flywheel BUT NOT THE AUTO. And the
other fits the turbo (Which I assume is different than the n.a. auto since
they don't list it there either). We may be stuck just trying to beef up
the existing flex plate.

I would not look upon it as being "stuck". I would now look at it
as being better :)
Ideally one could make a die and form thin 4130 to nest inside
the flex plate. Bond it in with RTV. That would allow motion between
the plates and damp the vibration. Unfortunately sandwiching it
between 4130 plates would help but it would move it towards the starter.
Perhaps we could space the starter out 1/16th of an inch.
Also lighten Tracy's damper plate to reduce its moment of inertia. Drill the
bolts and cut away low stress parts of the plate. I will do a sketch.
Let Jeff do this as he can set up a static balance rig.
-----------------------------------------------------
Here is the sketch. Use shear lock nuts instead of full size.
That will allow shortening the bolts a small amount. Every little
bit helps when it is out near the rim doing 6500 RPM.
We can also make a die for cutting 500 F silicone rubber washers to replace
the 200 F black rubber bushings.
