I took a photo of the drivers side from the trunk POV. That dark area on the bottom right is the fuel tank. sits on the "shelf" and extends under the harness mounts. The tank itself extends down into the trunk. The posts have 1/4" thick ~ 6"x4"gussets which you see here there are grounding terminals mounted. (The passenger side is another location also where I mounted my battery grounding, then continued it up front to the frame by the motor mounts). You can see the bolt on the plate where the harness is mounted. 3/4" studs in the top and a nut to hold down the plate. Plate is 1/4" thick by 2" wide.
