bought a 1957 chevy 3100 pickup. was told it was put together from three different trucks. as for the motor and trans i do know its a straight six. could very well be the 235 or 261 stove bolt. the transmission is most likely a 3 speed. stock frame with front and rear leave springs and drum breaks. also obtained extra top of cab, driver door, left front fender, tailgate, and bed running boards. she has potential.
