WooHoo!  I just found one that I was looking at earlier.  But my $100 figure was wrong.  More like...you guessed it...$250.  The $100 was just the stator.

        I wonder what the dimensions of these are?

        Here are some cheaper ones:

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.
