Well, whatever you do, don't seal anything yet. If it's the piece I'm thinking about, the little part in the corner for the visor, correct? You might be able to hit it with some heat, or a support like a Popsicle stick or something to support it from the inside. You might need to separate it from the bottom and realign it, or in a worst case scenario you may have to redo the whole stupid part! But in my opinion it isn't as bad as I feel like you think it is.
