The top of the line Generation 3 Impala SS is on the GM "B" platform beginning in 1961 You can have the controversial power brakes for an extra forty-three bucks. The '63 model is more squared up than previosly, while the SS features an aluminium panel full width, with a chromed border and the Impala signature three taillight configuration mounted centrally in the panel. The most popular engines for the '63 model year are the 283 and the 327. The vehicle in the images below is complete with the very rare factory dash-mounted tachometer at the base of the steering column.
