Dakota manifolds for A body

Valkman, do you have a manual box or power box. I think the issue with the LH dak manifold is interference with a power steering box.
Since I have an early a it's pretty tight in there, and had shave off .020" off the manifold and I used a smaller streering coupling. I do have a manual box, and I can't speak for the later cars but if works in mine I'm pretty sure it will work.
