Nonsense.....the wagon quarters are nowhere near a Barracuda quarter. Now if you need just a little patch panel down low, that section rear of the wheel opening might work but not as a whole quarter. There must be almost 2 feet difference in length alone not to mention the wheel opening shape is different and the door opening is totally different. As for the taillights, a '64 Valiant has unique taillights. The '65 Valiant is the same as a '64 and '65 Barracuda. The wagons all have taillights unique to their year.
