No sir. Lift the gauge and look at its backside.
That piece over one fuel gauge stud could be tossed in the trash. You need a real nut there, with or without the shield. You may need to clean a bit of rust off that stud before trying to screw a nut onto it. These studs a simply swedged into a fiber board and that board get warped and brittle with age. Don't what to break something more trying to fix first thing. To use one of the speedy nuts on this stud and add standard hex nut at different stud might be the better plan. They didn't hold much of a tolerance in manufacturing these studs. I've ran across a couple that a hex nut would not go onto. Running a thread die over them is nail biting experience know how easy the board can crack. Anyway...
What you have pictured there was replaced with a speedy nut in later models. In those, the nut and stud has a baklite cap over it that looked much like a household wire nut.
