So where can you get the little key that the rotor fits into?  It sheared right in two.  The stator/rotor are often packaged together.  I'm still searching.  I'll probably call nfieldgear.com tomorrow and work something out with those parts.  I guess that's the only supplier in the U.S.?  They don't seem to have all of the small parts and pieces.  E.g., I need one of the valve cover special bolt things, the middle sized one, but I have no idea how to find one until I run into someone with a parts bike.

For now, I'm beat by daylight savings.  I'm glad this bike is going to go back together without too much.  Is this kind of catastrophic failure of the rotor common?  I've seen people mention spacing the rotor or it can fail.  What a mess...

Only if the gap is not set or the hardware not torqued correctly.

 My advice is get yourself a Super Factory Service Manual, The Snidal Manual and the factory parts book for your Bullet.

 Yes Pete Snidals manual and The Super Factory manual have most of the same information but they are formatted and organized a bit differently from one another.  Each has a few small things the other does not.

 The parts book will quickly become invaluable in headaches saved by having the right part number when it comes time to order or talk technical.

Can't remember if it's a woodruff or square shear key but take the bits to Nappa. They should have a selection on hand.
 Trick to center the stator. Regular steel feeler gauge won't work. Cut soda can into strips for spacer/alignment shims.

I wrap the rotor with a strip of cardboard from a cereal box, with no overlapping ends, and use that to gap the stator. Then tighten the stator, and remove the cardboard strip. That does it.

Any car parts store should carry the woodruff keys, probably the square ones, too.

Advance Auto sells an assortment pack of the half moon style woodruff keys but I haven't ever seen the square ones in my store.

Or I bet Nfieldgear.com would have the rotor key also.  ;D

I use a strip of plastic cut from a milk jug.
