early a vs. 67-up exhaust manifolds

I didn't think the power/non power steering matters.. Since the 67-up engine bay is wider, moving the column away for the motor that manifold isn't as tight to the engine. I would compare the manifolds to the spitfires in width..
From all I read the driver side won't fit!
