Then the high tension spark plug straps, un-insulated and other wiring needing suppression devices, mounting a radio with a metal gas tank as a dash board, very little firewall room, figuring out a good antenna without drilling into Ford sheet metal, (the old running board antennas didn't work out very well, too low). On & on... Crosley actually made a "small" radio in '31 that clamped to the steering column with a small speaker box mounted elsewhere. Usually had the antenna attached to the chicken wire in top, but that would need to be verified that it wasn't grounded! It wasn't unusual to have the radio shop pull down your headliner and insulate the top's chicken wire from ground points of the body, then connect it up to the radio's antenna with a shielded lead-in cable, down through the A pillar of car's body.

i think all Ford car radios where positive ground till 1956 when they came out with 12 volts
