     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.

Reminds me of the flex drive plate of an NSU Ro80. It is also square 
and bolts onto the torque converter. The starter ring gear
is on the torque converter and not the flex drive plate.
