I have a pair that came from a 67 with a 273 numbers 2465 769 and 2780 845, if your interested. They were used on a 75 360 for a short time before headers were installed.
Just a FYI, the factory 67-up 273-318 A-body exhaust manifold's (I am speaking of the driver's side manifold specifically.... the rear dump on that side is in a little different location, compared to the 64-66 273 manifold, as on the earlier year's the rear dump is designed to fit around the steering column shaft for clearance of steering box and shaft. Hope this information is helpful to you all. Dodge33
