Dodge Dart Alargado (limo)

Like many of our cars of that vintage, it's probably been modified over the years. I wonder if it's a late '66 and/or started earlier than the U.S with the dual braking system and the Midland type booster. Looks like it has a later ballast resister, but, only half of it hooked up? I see a relay setup on the inner fender, maybe a Leece-Neville alternator?, and what are those orange items on the firewall? I'd for sure get some new hoses and 86 that plastic fuel filter.
