Currently reading the new book by David Wright (Vincent Motorcycles Since 1955) and on page 202 it mentions use of a Fiat 500 distributor on a Rapide. I googled a bit and the original distributor is still available for $198 (US). From the general appearance, some mods are obviously necessary. Anyone out there with experience or comments on this? There are also "drop in" kits available to covert the originals to electronic. I'm going to display my ignorance of what is feasible, because I am neither a machinist nor an engineer,but here goes... Create a tricorner adaptor plate, same shape as magneto gasket. The tricorner plate has a central hole. Drill two opposing semicircular slots in the lower "shelf" of the distributor. These slots,through which two screws fasten to threaded holes in the tricorner plate, allow adjustable rotation of the distributor body. The distributor shaft has to be sized down and may have to be keyed and threaded to allow fitting of a solid gear replacing the ATD. Now awaiting arrows in my direction....
