The alternator is held in-place by 4 bolts in the shroud, and a strap that holds it down to the stand that it's on. These are 10mm bolts, and only 1 is readily accessible by a mortal. Go ahead an take it out. There is one below that is right behind the intake manifold. If you're careful you can get that one as well. The other two screws are blocked by other motor parts, so we're going to have to do some more tearing down.
