A method of extending a truck cab includes removing the cab rear panel, providing a cab rear opening with an upper margin and two side margins. An extender joins the truck cab, the extender having a forward opening with an upper margin and side margins that are recessed. A top fillet and two side fillets join the margins of the extender opening and have curvatures that match curvatures of top and side corners of the cab. The extender is placed against the truck cab with the extender opening margins in abutment with the cab opening margins. The fillets are in flush contact with the upper corner and side corners of the cab. Bolts secure the extender opening margins to the cab opening margins.

The second multi-channel extrusion includes at least two tubular channels connected by a center rib, and having a joining end configured for joining at the predetermined angle to the joining end of first multi-channel extrusion. The joining ends of the first and second multi-channel extrusions are configured such that the center ribs complementarily engage as a joining surface.

The present invention relates to a sill of a vehicle body (1), comprising a lower sill part (5) and an upper sill part (6) placed on and attached to the lower sill part (5). The sill is characterized in that the upper sill part (6) is part of a vehicle superstructure (3), in that in one side of a first sill part (5, 6), which faces the further sill part (6, 5), a recess (7) and, on one side of the further sill part (6, 5), which faces the first sill part (5, 6), a protrusion (61) is provided, wherein the shape of the recess (7) corresponds to the shape of the protrusion (61) and the protrusion (61) interlocks form-fittingly in the recess (7). In addition, the invention relates to a vehicle body (1) with two sills (4) and a method of manufacturing such a vehicle body.

Disclosed is a vehicle rear wing structure, that includes a rear wing plate and a rear wing. The rear wing plate includes: a buckle portion, formed into an angular structure, and is used to clip and hold along a front end of the rear wing, so that the rear wing plate is fixed securely onto a surface of the rear wing; a main body portion, formed into a planar structure, and is disposed on a surface of the rear wing, and is connected and fixed to the buckle portion, on an inner surface of a rear part of the main body portion is disposed an adhesive portion; and a protrusion portion formed into a tilt-up structure, this tilt-up structure tilts up along a rear end of the rear wing to form a wind resistant plane.
