Trying to replace an alternator on a 2007 Lexus IS350?

I've replaced alternators before, on Fords and older trucks, but I can't figure out how to break this one loose. I know I'm likely missing a bolt somewhere but I haven't been able to find a diagram to see what I'm supposed to be doing. I've removed the plastic shrouds and have been able to remove the serpentine belt without an issue, and removed the visible bolts that appear to be holding it in, but I'm not even able to wiggle it at all. Any help with a diagram or if anyone with some experience with an IS350 can help, I'd be in your debt. I'd rather not dump $1200 into an alternator repair if I don't have to.

Should be just two bolts. It's not rare to have to pry them off. Use your head and pry against sturdy metal. You could damage the alternator prying it off but being your replacing it anyway it's not a problem. Just be careful and watch what your prying on and against.

There's a hidden bolt behind near manifold. 10 mm
