  • A new console held heater and air conditioning controls and accepted standard Delco radios due to its increased depth.
  • Early 1977 option listings contained CC1 glass roof panels ($200.00) but these were never available during the 1977 model year due to a marketing exclusivity dispute between Chevrolet and the panel vendor.
