Default [Q] Need a specific replacement part, LED notification diffuser.

So I cracked my screen a few weeks ago and it would have cost me $300 to replace the screen or $100 to order the part and do it myself.
Last night I took the whole phone apart, it's literally in pieces. However when I was taking it a part the adhesive around the notification LED diffuser got all mangled. I can't find it anywhere online, I've looked. I can find everything but that one piece.
Would someone have any suggestions or ideas where I could either find the part or a new piece of adhesive?

Thanks

Oh yeah it's the C6906 model.
