If the newer stator that you installed isn't bad, you could try mating it up with the newer CDI box from the bike the stator coil came out of. That sounded confusing huh! I guess what I am saying is, if you can't find the correct components for your bike, try using the complete system from a newer bike and install the stator coil on your stator plate as you have already done. Might be worth a try.
BTW I have been down this road too, my son's first bike was a 1983 CR60, and everything seemed to be obsoleted.
