Need Help

Are you sure you have the right manifold. I just checked some casting numbers last night. I have a left side that turns forward, 64-66 Dart/Barracuda, and I have one that turns back, 67-68 Dart/Barracuda. I just came across a 69 Dart on e-bay that shows what is supposed to be the original motor with the turn forward manifold and starter installed but out of the car.
