It's an old car, so I'd decide how much money is worth putting into the car. For example, if the automatic transmission has more than 150,000 miles on it, it may fail soon and be a major expense to replace. Try to restore the equipment to the original manufacturer's design, replacing the broken lines etc as well as rechecking the spark plug wires to make sure they're in the correct engine firing order and not crossed up. This all assumes the engine had regular oil and coolant changes. If not, that's another reason not to spend much money on this car.
