i gust got done with my motor on my 68 mustang and the cap and rotor is around 30 ish at any locall part place, i would drain the gas from the tank and put new gas, if it has points i would do but not being there it hard. It mite be safer to tow it home on a trailer first then go throw it. I have seen it where cars are going then just die and your dead on the side of the road. you can put a new battery in it and need a new altenater and not know it till it's to late. I hope you have Triple A for that road trip.
