[Q] Looking for headphone jack/speaker assembly? topic

My nephew poked a pin through the rear speaker grill of my brother's AT&T Moto X and totally killed the external audio. I'm looking to help him replace the headphone jack/speaker assembly, but the cheapest devices I can find on ebay (won't charge, cracked screen, bad ESN) that I would use to rob this assembly from are all going for well over 0.

I'm also having a heck of a time finding a spot for such replacement parts so I'm guessing they don't exist. Anyone have any clues to track down such an assembly, or have a busted X you're looking to part out? :P
