Cool deal, man. Great score. There's something really cool about using these cars as intended for the seemingly mundane driving chores. It makes them less mundane and is such a treat to see my old mopar parked on a city street or shopping mall parking lot. I ditched my modern driver a few years ago for a 73 /6 Dart. To say it's a "daily" driver is not quite accurate, I've got a "late model" 1994 Ford van for work (I'm a painting contractor) , but the Dart takes me everywhere else after hours, rain, shine, or snow. Even took me 8,300 miles cross country last year without a hitch.
A few other points for making a reliable driver. I inspect or replace EVERYTHING that could leave me stuck: belts, hoses,vacuum hoses, brakes, lights, ignition, starter relay, ballast resistor, voltage regulator, water pump, etc, etc,etc. Don't overlook the less obvious like throttle return springs, and clips for your tranny linkage etc. I keep the known good take off parts in the trunk with a tool kit, some spare wire, electrical tape, butt connectors for making repairs, fluids, rags, latex gloves etc. Nothing ruins the novelty and enjoyment of an old driver like being stuck in a parking lot somewhere over something easily fixed but not having the stuff on hand to get it done. Also, go over any visible wiring for loose, dirty, corroded connections or cracked wiring,
Also, don't overlook the things that many fair weather only cars often get by without: working defrost/defogger and other HVAC features, working parking brake system, windshield washers and wipers etc. They will make thing more enjoyable as well as safe.
You're in California, so I won't get into the steps I use to guard against winter driving perils to the cars sheet metal.
Anyway, hope you enjoy the experience as much as I and others here have.
