Roadtrip

i just got my dart on the raod today after a winter restoration. its a 73 dart 4 door, with the 318 and 904. im taking it on a 1500 mile roadtrip in 2 weeks, and im wondering what all i shold bring with me for spare parts, of things that might go wrong. i have changed all the belts, hoses, lines, fuel pump, brakes, radiator, thermastat. i guess my question is what things might go out without notice, ive already been told to have a ballist resistor and ecm. anything else?

this is my first classic mopar, so any help would be great
