link

in the image you can see the area i want to remove.

I solved with:

#gk-tools {
display: none;
}

in override.css

... comment gk-mass in layout.css

/*.gk-mass {
clear:both;
margin-bottom:23px;
}*/

and comment other code in template.css

#gk-contentwrap { overflow: hidden; background: #fff; /*border: 1px solid #f0f0f0; padding: 18px */}
#gk-main . { /*margin-top: 23px;*/ margin-bottom: 0!important; }
#gk-top-nav { /*border-bottom: 1px solid #f0f0f0;*/ margin: 0 0 35px; padding: 0 0 10px; font: bold 10px Arial, Helvetica, sans-serif; text-transform: uppercase; color: #777 }

I don't now if it is the right way. but it works........
