Hi=20 Ernest,
 
This is = a nice thought,=20 but I don't think it's going to be quite that simple with Tracy's = drive. =20 There isn't a ton of space between the back of the drive adapter plate, = and the=20 flex plate.  There are lots of bolt heads on the rear (engine = side) of=20 the plate that hold the drive in place as well, which may or may not get = in the=20 way, depending on the diameter of the stator.  The dampener plate = is on the=20 front side (prop side) of the flex plate, and would provide a nice = mounting=20 point for the rotor, again depending on diameter of the rotor.  The = rotor=20 would have to be bolted, or riveted to the dampener plate securely, = since there=20 are no splines accessible.  The center hole in the rotor would have = to be=20 enlarged to clear the hub of the dampener plate as=20 well.  
 
Do you = know the diameter=20 of this unit, and the thickness?  I do think the idea is the best=20 I've heard, but it might take a custom built unit to do=20 this.  I would bet we could get someone to build one,=20 since everyone who's purchased one of Tracy's drives could use it, = and=20 would probably want to.
