Dave,
My engine still has the part that's bolted to the block. It looks similar to yours, but hard to tell as it's behind the exhaust pipe. The orientation is correct. Mine is currently blue, but a PO might have done that when the engine was repainted many years ago.
My clamp is missing, so I can't help with that. Maybe this accounts for why the front engine boss that the exhaust manifold was bolted to was broken on my car. Too much movement of the exhaust pipe. I had to reconstruct the boss out of J-B Weld. It looks pretty good. And seems to be holding up just fine. Hard to tell it was even repaired.
