I've got an old Zenith cabinet radio from the late 40s myself. I'm taking the easy way out though. Mine has a row of three knobs across the bottom of the dial. They are about the right spacing for an old model shaft type car radio. I'm going to one day strip the chassis and leave the original dial in place and mount modern guts, probably a car radio but may rewire a small portable instead. I know it's not restored, but I'm not so interested in value. I will keep as much of the old chassis intact as possible though, just in case someone wants to attempt a total rebuild later. It would need everything replaced and rewired -- it sat out in the weather a few years but I managed to save the cabinet, just had to replace one leg that rotted. I used black velvet on the speaker grille -- looks good anyway!
