You will be lucky as that thread was end of 2017. But good luck on a response.
If not, you can get them new or secondhand on Ebay as they are just bolt on at reasonably good prices.
(usually from £120 or more)
Last time I looked, buying them from the dealer was around £170 +vat (not fitted).
I have this dilemma myself, as the base model Ecosport (Zetec trim) does not come with roof bars.
As I bought an ex-demonstrator 2019 Zetec, the price was 'take the car as is', so I never bothered asking about roof bars. Now i am thinking about it for my peddle bike, do I fit the roof bars with cross bars, or fit a Saris Solo rear bike rack for rear door? Choices Choices, he he.
