it was sort of a baited question ,

since 1972 my dad has owned a 1957 300C convertible 392 Hemi, with a 3-speed on the column

i believe there were only 17 cars built with the 3-speed manual transmission, which cam with a higher horsepower engine and special camshaft.

there is a vin list of those 17 cars because there was a recall for the camshaft because Chrysler was concerned with premature failure of the camshaft due to the heavy duty valve springs

my dads car is the only convertible on the list

its pretty much a survivor with 1 repaint
