Early 1951 Kaisers used the same GE radio that the '49/'50 Frazers used. It had plastic knobs with chrome bezels. Later 1951 Kaisers, and this would include all 1952 Virginians, which were unsold '51s re-tagged as '52s, used the Delco radio which has chrome knobs and bezels. The bezels are not the same. The early radio, with the plastic knobs, used a bezel on the volume knob which operated the tone control, and used a splined "dummy" on the station selector which pressed into the plastic knob and had a hole in it for the set screw to fasten it to control shaft. The volume control bezel may be a suitable sub but the one for the station selector is totally different and will not work as a sub (at least without modification).
