Got a set fitted, had same issue with the two front windows which turned out to be the window seal gets curled on the rear most edge of the front deflectors. Teased the rubber out with a thin piece of plastic like a bank card which sorted it out. There was an odd amount of metal clips to hold them in but concidering they dont seem to be big enough for the front deflectors wasnt a problem.
So if you want the Heko wind deflectors they fit despite what the ebay seller says.
