I'm not sure what a "bow tow" is, but I'm assuming the "wing" nut is rusted to the threads? spray the threads with penetrating oil like liquid wrench, chase the threads with a die if they're not too far corroded......cut if those first 2 options don't work. Likely if the oil helps break it loose you should be able to take the nut off.
Hope that helps. i want to see that trunk well. What a nice trunk floor!!
