FI badges are held fast with 3M Auto Trim Tape. Trying to fit the old badges to FI tanks has been explored by myself and two other members here. I loaned them the Badges for their ideas as how to go about it. I finally came to the conclusion that with two compound radii to contend with, the easy answer would be access to a Cincinatti Milacron with a LADAR (Laser-Radar) profiler option for milling out transition sandwich plates for a decent fit. But if anyone wants to take me to school on how to pull it off, I'll be an apt pupil.
