In upgrading the Advance Design 1947-1953 cab for 1954, GM engineers created a totally different dash assembly. It required that the radio be much smaller. With better electronic technology and no push buttons, the new 6 volt radio could be placed into the smaller space. They even placed a cardboard sheet above the ’54 radio to protect it from settling dust over the years.
Yes, the 1954 Chevrolet and GMC had different designed dashes but each of their radios were similar and fit the smaller area. In the follow photos you can see the major differences between the 1947-1953 and the new 1954!
