Ok... which one of you did this!!!

When parts come back, I always check them. They're taken out of the box and checked out thoroughly. If there is any indication of it being installed, it doesn't come back. Electrical and special order parts don't come back period.
Way to many people buy a part, install it and that doesn't fix their problem, then want to return it. Nope!
In all fairness, I have seen Mopar send cores out as new parts. Happened a couple times with 604 transmissions. PIA to send back to Mopar as a MRA. I've also gotten parts that were dealer returns with the wrong part or missing components and my pet peeve, pre installed.
