Upgrade for my charge system

I posted earlier about my '76 750's charging system. I found out that my exciter wire is broken inside the cover... So I am wondering if any body knows where I can get a stator and rotor from a '78 and later kz 750. It won't be a good as the brushless system, but I figure I can bring it up to date as far as finding parts. Thanks.

Others have tried to mount a 78-80 rotor/flywheel to the 76 crank, and it will not fit.

Best idea is to fix yours.
