Dad's 58 Desoto Firesweep convertible is a 350 with California emissions. One year only-looks just like a 383. Here's a weird mopar myth......in the 70's mopars-not sure of what all years-if you put your hazard flashers on, and step on the brake pedal, the flashers will stop. Keep your foot on the brake, and gently work the hazard button back in, and the radio will come on with no key! I found this out on a charger I had, and a few friends did it on a dart sport and a cordoba.
