What I did on my 52 F-1 was I had an original radio which had a huge heavy chassis to it with all the original tubes and other components in it, well that all got taken out and replaced with digital components and circuit boards, which meant that the huge chassis could now be shrunken to a very small size and light weight. I would recommend going that direction. You gain a really functional radio, Bluetooth, AM/FM, USB charging point and or thumb drive. Lots of way to listen to music take or make a phone call and save lots of room to boot. It was done by an Aurora Digital conversion they specialize in taking old car radios and converting them to digital units.
