Hi Norm and AVB,
Yes Briggs made it more difficult than it needed to be with about 30 different stators plus all the different wiring .
The easiest way to know what you have is to do a test or get the part numbers then do a search.
As far as I know with cars the RV1 Valiant from 1961 had Alternators and was told Holden EH had them but only as a heavy duty option
and alternators were standard in the HD Holden.
Cheers
Max.
