My 76' Scout has a heavy skid plate under the fuel tank. I ( like most ) am having trouble with the fuel gauge and wanted to verify the sending unit but didnt want to mess with the rusted and seized bolts holding on the skid plate. I carefully cut an access to the sending unit which is placed between two body struts. When I'm done with the rebuild I plan on covering my cancer ridden rear deck with a sheet of diamond plate ( after sanding and priming whats left ). I will have a hinged access to the sending unit for future replacement.
