The engine is offset towad the passenger side by 1-1/2", not toward the driver's side. The pinion shaft is offset toward the driver's side, amking me think the angle should be toward the passenger side rather than the driver's side. I've yet to have my car on a lift.
You can replace the exhaust manifold gaskets with copper gaskets and the exhaust leak problem should go away. You'll probably have to unbolt the compressor to get to the manifold, but you shouldn't need to undo the plumbing.
