Vespa VBB MAZZUCCHELLI crankshaft modified for PX ignition

Hey,

 

I've a VBB 1T vespa from 1962 which I'm restoring. The foruims I've seen almost every one complain about the lights and because of that I would like to convert to 12V. I'm thinking to put the Mazzucchelli crankshaft modified for PX ignition:

but I've some questions about which Stator Plate and Flywheel to buy.

Can anyone help me

Tks
