Mazzucchelli and Vespatronic

Hi, I'm working on a 1957 Vespa with a VBB engine and I bought a Mazzucchelli Art. Nr. 45131000. I would like to know which is the best ingnition to mount on it. I'm thinking on a Vespatronic, but in the specifications it says to be mount in a PX crankshaft and I don't know if they have the same size. Best regards, Jorge.

Hi dude


I guess you`ll can use  the vespatronic ignition (item code 50004000).

What engine number do you got ?
