2003 S40 roof bars?

[ThisInJapanese]

I have a 2003 S40 shed that I'm running for the time being, and I'd like to find some roofbars for it, but none of the normal sites that I would go to list anything that works with the car.

I have some Whispbars that I would like to use, but there is no sign of the compatible footpack being available again.

Does anybody have any suggestions as an alternative?
