I am having trouble understanding what you are dealing with.
Does the hood rattle when it is closed?
You say that, "I can lift the hood skin away from these brackets." Do you mean, while the hood is open?
I know that you can't see exactly what is rattling with the hood closed, but are you absolutely sure it is the hood skin rattling against the brackets?
I have seen a lot of these hoods and have never seen one where the skin could contact the brackets.
Did you, by chance loosen or remove the center bolts which connect the two brackets together at some point? This would cause your type of problem.
