I have never had a problem with a Wells part including the VR706 that is the topic of this thread.
FWIW, the cam position sensor in my wife's PT Cruiser started acting up and Autozone was the only place that had one in stock. It was in a Wells Box but inside it was in a sealed plastic Mopar bag with a Mopar Part Number. So whom ever makes the part for Mopar is also selling it to Wells.
