They have a 40A unit.  The hole in the rotor is sized for a 1", 10 
spline shaft.  That matches the shaft from my sun gear exactly.  Now the 
only question is if there is enough room on the spline with the PSRU 
installed for the rotor to fit between the flexplate and gearbox 
housing.  The generator is only 1" high, so I don't think that is a 
problem.  It is rated for 2800RPM, but it is a small thing to rewrap the 
coils to give more current and less voltage.
