Hi folks, new guy here. I recently bought a 2012 Titan with the 40/20/40 front seats and the middle seat back/armrest I would like to replace with one that has storage inside. Mine is just a giant box with two cup holders and I'm finding it hard to find any place to put change, pens etc in the truck. is there a bolt on replacement available? I've searched in vain and was hoping you folks could point me in the right direction. Thanks!
