Fits perfectly on my 05 estate and has been very useful

Just bought one from my local vauxhall dealership to fit on my new shape 04 vectra estate without factory fitted roof rails. The side flaps do not sit flush with the roof of the car. The metal brackets of the roof rails extend a good 40mm before locating into thevehicles roof slots so that the flaps are ending 40mm above the roof of the car and look awful. Consequently theres a lot of bare metal showing and plenty of water access into the open slots of the vectras roof which is unnacceptable. To be returned to the dealership to see whats going wrong. Part numbers correspond with this one perfectly.
