Black/Gray mod from two to one discharge

A friend of ours looked into getting his 2015 Tab changed from two discharge ports to one.  I told him that someone here, Dale... grin... came up with his own method.  Bill heard that they also were available as a kit from the factory and since he needed to go thru a dealer, he called two of them a few weeks ago and never heard back.  I suppose that either there is no kit, or there is a fault in communication.  He doesn't want to install it I guess.  So...  Does anyone know if there is a kit from NuCamp?
