Genuine Volvo roof bars to fit Volvo S40 or V40 (1995-2004), if you have one of the ones with no roof rails.
I think the part number is 30806698 and 30805400
The feet screw into threaded holes in the roof of the cars (which sit underneath the plastic rail that runs along both sides of the roof there are 4 push in caps covering the screw holes).
Complete with the 4 bolts for securing.
These genuine items give a very neat looking fit and are shaped to fit the roof line perfectly. They have a different shaped foot profiles and are labelled eg. front left, front right, or rear.
They are relatively heavy and long, so will be sent by reliable UK courier but would prefer collection
Looking for £30 + £5 for postage.
