Abstract: An after-market antenna for a vehicle includes an elongated body having a top end, a bottom end, and at least one peripheral side. The bottom end terminates with an axial bore extending partially through the body and adapted to receive an antenna wire within. The axial bore includes threads at the bottom end of the body that extend upward at least partially through the axial bore for receiving a conductive threaded shaft that projects out of the axial bore and that is adapted for screwing into a threaded antenna aperture of the vehicle. A first groove is formed around the body and has a back wall substantially circular in cross-section except for two opposing parallel sides adapted for contacting two opposing sides of a wrench that has a thickness that is smaller than a width of the first groove. Various extension pieces and top pieces may also be included.

Abstract: A valve stem cover includes a cylindrical cap open at a bottom end thereof and threaded with threads on an inside surface thereof. The cylindrical cap is adapted for threaded engagement with a threaded tire valve stem that projects through a wheel rim. A skirt projects downwardly from the bottom end of the cylindrical cap and is adapted to cover substantially a lower portion of a threaded tire valve stem that projects through the wheel rim. A decorative top portion projects upwardly from a top end of the cylindrical cap and can be removable for interchangeability.

Abstract: An interchangeable face gauge structure for automobile gauges comprises a gauge body, a face gauge, a retainer ring and an outer cover. The gauge body and outer cover are combined by means of assembling, which causes the outer cover to be dismountable from and re-mountable on the gauge body. The face gauge is additionally mounted on the surface of the light directing panel on the gauge body, which allows the face gauge to be replaceable with one of the type to the liking of the user after the outer cover is dismounted from the gauge body, improving the variability and visual effect of the gauge body. Further, with the convenience of the outer cover being easily mountable on the gauge body, the user is allowed to replace and mount parts by themselves, adding to the practicality of the structure.

Abstract: A lug nut system for a wheel includes a rigid body having at a first end a tapered rim and a threaded aperture adapted to engage at least one threaded stud of the wheel. The body includes a tool engagement section, and a threaded shaft at a second end of the body adapted for receiving an ornamental cap. A cover has a first open end, a sleeve adapted for fitting over the body, and a cap at a second end that includes an aperture for the threaded shaft of the body. Preferably the sleeve has a cylindrical inside surface, such that the sleeve is free to rotate when in place over the body, thereby inhibiting removal of the wheel. The cover further hides any tool marks on the tool engagement section of the rigid body.
