YES 5.9 Magnum manifolds work in early A bodies. Here is exactly how!

Does the steering shaft rub on that manifold?

It looks like the steering shaft is being pushed down and to the side, it should be in the middle of the column jacket. But that could just be the angle the picture is taken from?
It’s not rubbing as far as I can see. I probably do need to adjust the jacket so that it sits more centerline
