I see now in my parts book that '63s use different manifolds than '61s and '62s. '61s and '62 used the same manifolds whether it was dual exhaust car or not. '63s used the one manifold on the passenger side whether it was dual exhaust or not. Driver's side manifolds had dual and non-dual exhaust applications. Assuming '64 is the same.
