I found some information on John Regan's "Fun Projects" voltage regulator that delt with the components that it's made with and more than one of them are obsolete. I'm sure that there are more modern components that can be substituted but it takes a person like John that is familiar with this stuff to do that. I don't know if the current owners of the design have this capability or not.

The generators that also mated to the cooling fan were designed with front bearings that could withstand the load that the fan adds to the design. Some of the later generators may not be as robust as the OEM ones were. I heard of folks using fans mounted to alternators and then experiencing premature failure of the bearings with them. Mounting on the intake manifold also varies somewhat so that also has to be considered. I'm sure there is nothing that can't be overcome but it may take some work to get there.
