The commonly available aftermarket voltage regulators that are compatible with the Magneti Marelli charging system do not bolt directly onto the original voltage regulator bracket. Drilling holes in original components is always a bad idea. Charlie Mullendore of Antietam Classic Cycle created the following intermediate bracket that solves this challenge nicely. In Charlie's own words and photos:

None of the voltage regulator mounting holes line up with the holes in the bracket.

An adapter plate is necessary. Here I've made a cardboard pattern.
