Doesn't have to be for the Carrera body. Several of the 911 bodies have buckets the same size. You only get half the H parts bag for the Carrera, and the trunk and light buckets that come with the 934? are cut off the same sprue. The only ones that won't work are the ones that have more of an angle. The Taisan 911 also comes with the correct buckets for the Carrera; They would all take the same light bucket H parts, The Carrera just doesn't come with this one, but funny enough comes with light decals and also the transparent headlight decals.
