As for whether the manual flywheel could be used in place of the flex plate, I don't know as I don't really understand how the PSRU hooks up.  I know the flex plate is different "somehow" as it takes yet another kind of starter.

Dave,
 
   You may be right...............I am not at the hangar now so cannot do serious measureing............They sell a different flywheel
block for the automatic...........It nests around the counterweight................I think it is different than the manual flywheel blocks
so as not to subject the thin auto flexplate to the 350 ft /lb torque to loosen and tighten the eccentric nut.............Will measure
both flexplate and steel flywheel (diameter, fore , aft , etc) and report as soon as possible................The flexplate and steel
flywheel both have 125 teeth which I hope indicates the same diameter.............<:)

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"


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.
