Changing the alternator on a 2000

What is the procedure for changing the alternator on a 2000 Montana? Every detail would help down to the size of sockets to use. I cannot see the back bolt to remove it. How do you get to that thing?

I don't think you want to know! You have to remove the belt, the power steering pump, the belt tensioner, and then tilt the engine forward to remove the alternator.
