Exhaust manifold for 318 swap in 63 valiant

The later 318 manifolds were already on my 65 Dart when I bought it. That's about all I remember as that was 30 years ago. Shortly after I got the Dart, the 318 took a dump so swapped in a later slant which has it's own set of issues concerning the oil pan. When you're young(er) you made things work as there was virtually no info back in that day and time.
