Here is a pic of the metal mesh behind a '48 passenger car radio grille.
< CLICK > '48 passenger carJust to clarify a confusing term ...
The term "radio grille screen" might be interpreted two ways and refer to two different parts of the radio area of the dash.
The wire mesh or muslin "screen" is permanently attached to the dash or to the removable section in front of the radio speaker. There is no wire screen or removable dash section on my '54.
There is also a "radio grille screen" that is cardboard. The cardboard "screen" was installed at the factory to hide the wiring and mechanisms behind the dash that would be visable through the opening for the speaker. The cardboard radio grille screen was to be removed and discarded when a radio was installed. I betcha most of them disintegrated and fell off over the years. It was on passenger cars and on trucks.
The Chevrolet Radio Shop and Service Manual for 1951 Passenger Cars and Trucks describes the cardboard screen in trucks on page 47, step #7: "Remove the decrative plate, the two buttons from the center of the instrument panel and the
black cardboard baffle from the rear side of the radio grille."Similar instructions for passenger cars on
p. 6, step #9The '54 Accessories Installation Manual for installing a manual radio in a truck (Step #7, page 92, and illustration #213, page 93) states to "Remove the radio grille screen and discard." The 1954 passenger car section describes the screen to be removed as "fiberboard"
