General Ford Flex Discussions • Crossbars from Amazon?

I have valiantly failed to find crossbars from Amazon that would attach to the factory oem luggage rails. There are the two I tried and returned.
-Komsepor Car Roof Rack Cross Bars 55” Thick Aluminum Crossbars Universal Roof Rack Adjustable Roof Cross Bars with 200 lbs Load Capacity Fits Most Vehicles with Existing Raised Side Rails with Gap
-COWVIE 123cm Roof Rack Cross Bars Adjustable Aluminum Cargo Bars Fits Most Existing Raised Side Rails with Gap -1Pair (White)

Anybody find some cross bars from amazon that fit the thick flex luggage rails?
