Has anyone taken apart the "wall" or partition that is behind the seats? I am looking to install a fire extinguisher in that area and I am looking for body metal to mount the brackets. I thought I saw someone's photo of the rear area when they dismantled it for a subwoofer...but now I can't find the pics. Any help here would be grateful. I thought about a bracket for the front of the passenger seat as another location... Any ideas?
