Gas tank and sending unit almost ready

Well ive been real busy around the home and needed a break. I said screw it and brought in the gas tank to put in the sending unit and give it some paint. It was a ***** to get the unit in but I did. Put a bit of lube on the seal and tightened it up. I need help with the pad. Does it go like I have in the pics? Does it lye on the top and the cuts on it go down to the lower section..IE: spare tire area? I had no pad on my orig.tank. Thanks
