How do you replace battery on 1995 Grand Prix?

I am assuming you know to remove both cables from the battery and any hold down that may be on it. I am also assuming you are baffled by that metal bar that angles across the battery. Yes it has to be removed. You can see the obvious nuts but there is a nut that you get too outside the engine is in the front wheel well and is surprisingly not that hard to reach. A simple solution is to go to an Advance Auto and get a new battery and they install it free in my area. Yes even the girl clerks install them.
