The headers are "New" been out since Oct 2013 I did not find any body that had tested the fit back on a E body in January when this Mess started.

As for If every thing is right on My end? I called several times to check with the tech Guy. He did not Know anything about these Headers, said he would research it 3 1/2 weeks later I still can not get a return call. Yet there is a clock ticking on the return timeline. It had been 6 weeks since the charge was made on my card.
