I also entered this post in "Roof Rack for 2014 TC"
The Ford dealer would charge about $520 per rail [$1040 for the pair] for my 2014 TC Van. It's the same roof rail available as factory option for the TC Wagon only, not the van. And the dealer would not install the rails, because they wouldn't remove and re-install the headliner.
At American Van, I ordered Van-Tech "Universal Roof Track" - 6' length, for $180/pair, [also available in 4' and 5].
Installation was $150. Total for roof track w tax and installation parts $356.
The rails fit in the groove of the roof. The installer had to drill new holes for the roof track, factory holes didn't match the track.
Then buy Thule Podium Foot Pack #460, and Thule Fit Kit 3101, and Thule Bars [make sure the foot pack is square or round to march the cross bars].
Just installed the Thule rack today, fits the rail perfectly. Ready for windsurfing, SUP, and saved plenty of moolah.
