800 mile roadtrip

I'm heading one state over to visit some family this Christmas. It's going to be roughly an 800+ mile road trip (one way) in my 71 Valiant 225 \6.

Any suggestions on spares or tools I should bring along? I mostly keep a pretty well stocked tool kit in the back, along with plenty of the most important fluids. It's had a lot of work done on it since I bought it, with new brakes, rebuilt fuel makeithappener, new fuel pump, new rad, rebuilt power steering (still leaks, dang it), new tires, new belts, new lights, new fuel hoses, new rad hoses, new vacuum choke, tested vacuum advance, new sparkelators, new plug wires, new cap, new rotor, new voltage regulator, new batt-tree, new fuel sending unit, and probably more I've forgotten. Heck, I even replaced that heat riser tube under the air filter.

I have a spare set of points in the glove box if the pertronix poops out on me, along with the matching coil and ballast resistor.

Anything I've missed?
