Hood Fix?

If I'm not mistaken, what is needed inside must be able to move fore and aft within the hood. What is wedged inside now looks like a 1/8 plate about a 1/2 wide and about 7/8 long with "threads" or a nut welded to the back side on both ends to keep it captured in a "reversed, upside down chanel" to allow it to move back and forth while keeping it from falling out while moving the hood around.
