I got it changed today (in the freezing rain no less

)
It wasn't too bad but the alternator bolts are a PITA. I am guessing they haven't been off since the factory and they ain't easy to get to either.
There is 1 you can see up top, and 2 under the alternator, all 15MM size.
But once those are broke lose and off, just swing the alternator out of the way(with belt off of course) and use a 1 1/16" Socket for the Oil Pressure Sending Unit.
After that, it is easy, it all goes on like it came off
