Paul, with all the recent discussion of flywheels and dampers I'm
confused (again). I had though that Tracy's arrangement was sort of the
standard based on successful flight hours. I understand that his
coupling has undergone a gradual softening with improving results and I
thought I understood how his unit was put together. Now i'm beginning to
wonder. Do you have, somewhere in your seemingly infinite files some
photos, dwgs, or Rhinos that would show this confused newbie what
Tracy's coupling really is made of and how it goes together?  Fred O.

Its is made of a square flat aluminum plate riveted to a Ford flange with splines.
There are four rubber bushing aluminum sockets riveted to the four corners.
It is bolted to the stock auto tx flex plate with four bolts that
pass through the rubber bushings.
Nylon washers are used to provide a bit of friction damping.
