B7 cab wings will bolts directly onto a b6 cab, only reason the saloons and avants are different and need cutting is due to the b7 having a swage line running down the entire car and the b6 doesn't have this but the b7 cabriolet doesn't have the swage line going along it so there is no need to cut the wings. The b7 cabriolet is exactly the same body as the b6 cabriolet minus the bumper, headlights, bonnet, wings front panel and rear lights. B7 saloon every panel is different to the b6 hence it being harder to match the front wings to a b6.
