One last engine problem had to be resolved. Oxygen sensors had to be put in the exhaust pipes. The decision was to use the later model 5.0 manifolds (the lower one in the photo) with the O2 sensor holes already machined-in since the exhaust system needed replacing anyway. The problem was the clutch linkage was right in the way of the downward turn of the manifold. An old trick came into play by cutting a section from the cross-shaft and moving it out with some flat stock. With proper bracing, it allowed the cross-shaft to pivot around the manifold flange.
