After hours of research and google searches, I was able to find this part. In case any one else runs into this same problem. The part is called a "Heater Tube" Motorcraft Part Number KT84. You can get them at rockauto.com
Apparently the tube is pressed into the lower nut, also from my research, this nut is no longer available. I haven't changed mine out yet, but the old tube can be removed by prying the heater tube and nut apart. The new tube presses into the nut and your all set.
Once mine comes in I will provide an update on how easy/difficult the repair is.
