When restoring the interior of your classic squarebody it is essential that you get the correct button for the horn on the steering wheel. Brothers Trucks has exactly what you need with their silver Chevrolet horn button for the 1978-1991 C/K Series trucks and 1987-1991 Blazer/Suburban. It is manufactured just like OE using new tools which guarantees an excellent fit, then vinyl wrapped to match the correct leather grain.
