Our boxes do have a plate. You have to remove and disassemble the box to cut the plate out. Not a quick job. I did mine when I had the bike apart for my big bore install. Plenty of time for it then! Can't really say whether it's a worthwhile mod. I did so many mods at that time that I have no way to make a comparison.
Howbeit when He, the Spirit of truth, is come; He will guide you in all truth:
