It's there to let the engine crankcase vapors be drawn into the engine and reburned. If you just stick a breather in the valve cover it will vent the vapors into the underhood area. It's an emissions thing and won't hurt anything as long as you plug the end in the carb spacer. If you have emissions testing in your state they will fail you if they see it. It may not be that critical on that old a vehicle.
