Two thing to be careful of guys:
-that stator is delicate. 
-the mounting holes are keyed.  One mounting hole is offset, so the 
stator can only be mounted one way.  The wires come out one side, and 
that side MUST go against the PSRU.

I went to a local motorcycle repairman and got him to give me a damaged 
unit that I could use as a template for drilling holes and such.  I cut 
a chunk of aluminum down in the lathe.  The ID I made a push fit over 
the PSRU input shaft.  The OD of a step I made a tight fit for the 
stator (once you remove the wires, the stator breaks apart into 
sheets).  I used one of the stator sheets to locate the drill locations 
for the mounting screws.

The parts are a standard size.  I suggest that if you are considering 
this, that you visit your local Harley repairman, and ask what he's got 
in his trash bin.  I've got the rotor housing (a truly heavy chunk of 
steel) and the stator "sheets" if anyone would care to have them.
