Need to find part not available at iFixit store
I've taken my iMac apart due to the problem described in Tip of headphone jack stuck inside port, and it looks like I need a new part. However, iFixit doesn't sell it (it's a ribbon cable that connects to the audio in and audio out ports).
The local Mac store said they'd fix it for $170, but that they have an agreement with Apple that they have to do the repairs themselves (boo). Does anybody know where I can buy this part? (for clarification, this is an iMac 11,1)
