V6 Mechanical Advance Electronic Ign Distributor?

Looking into carbing or Holley Sniper on my V6 that was replaced with 5.9 Magnum in '89 P/U.
The V6 is an option for the Willys CJ2A project, however, is there info out there on converting a V6 distributor (computer controlled type) to one with a 6 point reluctor, similar to the standard OEM V8 electronic ignition distributor, but with maybe a slant six point reluctor and having mechanical and vacuum advance? What have folks done on this situation?
