My fear is, if someone screwed up their housing(s) that bad, they probably just chunked them.
Good luck though
Might I suggest you go ahead and purchase a whole new housing to fix your problem, but keep the busted one and you may be able to do the inverse. Get on ebay and sell it as is.
Or at the very least, maybe the guys at AAC would like to have an extra sitting around, "just in case."
