the 1954 Chevy Truck Radio I have does not have a speaker-I know I can purchase the speaker-but what kind of frame or hardware is needed to do this? I have seen picutures of 1954 Chevy Truck Radios on ebay that seem to have a black cardboard cover over the front of them-where would I get one? I have been told there is a frame to hold this radio it that what I need? Thanks RHuddle56
