I think that the Ford joints are made by moog and the Napa premium joints are made by TRW. This is kinda like the batteries, there are only a few plants that make many products and lots of other names go on the box.

Just got off the phone with XRF chassis They are about an hour from me. All their stuff is made in Taiwan. I asked why they parts were not made here and the reply was ' because we control the quality in our plant in Taiwan ' Not very impressed with the help there. Not very knowledgeable, not a good sales person either.. Anyway, the parts can be ordered at any AutoZone or Advance Auto parts stores. Million Mile wty on personal stuff, 100k on commercial stuff. They only cover their parts, no labor, seals, etc. So, even when these go bad, you are still out $100 in seals.
