How do I make it look the same with putting the pageWidth back?
Put pageWidth back and then modify your header background image. Use the gray and black background bars from your navTabs and tabLinks and put them on the bottom of the image. Set the height of the bg image to the same as the header. If aligned correctly the header background will line up with the backgrounds of navTabs and tabLinks seamlessly.If I put the pageWidth back it will look like this.
