I have one by one been replacing bits of my FJ55 adventuring rig with metal. Now I am on the rear interior. Can someone please explain what the metal cover is for? There seems to be no bolts in the fuel neck, only a rubber seal. I want to cut and bend the hump out of the floorboard and put a straight sheet of steel in place of the liner. Am I missing a reason not to do it? Thanks, Captain Yarby.
