The 1955 - 59 truck radio works if you have 12 volts or use the 1953-54 passenger car manual radio if you have 6 volts. I believe that the passenger car radios have the speaker attached to the radio where the 55-59 truck radios used a remote speaker. They all fit the original hole in your dash. I collect radios and have a couple of the truck radios. If you look on ebay you can get them from $10-$150. Be patient and you will find one under thirty dollars. .........g
