Parcel shelf cover removal 1939 Hudson Six

I have decided to go with the 3rd brake light option as well as putting red LED bulbs in my taillight housing of my 39 Six. I will add the 3rd brake light to the rear windows. So, to run the wiring into the trunk how would I get the Parcel Shelf cover off? Could I simply tale a small screwdriver and pry around the edges? Or maybe just remove the backing panel in the trunk? Any and all suggestions welcomed and much appreciated!!
