The Impala was redesigned for 1965, when full-size Chevrolets swapped the X-frame for a full-width perimeter frame. The new body brought curved, frameless side glass on pillarless models and redesigned full-coil suspension. From 1967 to 1969 an SS427 model was also offered. The one we have is a 1967 Impala two-door set up with hydraulics.
