Exhaust vs power-steering

Just wanted to bump this thread back up again...

just to recap; I've gathered that none of the stock manifolds or any available headers will clear power steering in a '71 Dart... that seems pretty clear now..

But, does anybody know how much space there would actually be between a new hemi and the power steering box?? What I really need to know is if there is any space at all to work with for fabricating a custom tubing manifold or if this is completely unfeasible??
