Crash Test Ratings:
N/A (No standardized crash testing existed for this era)
Braking System:
Hydraulic drum brakes all around (standard). Disc brakes were optional on front for later C2 models, but not standard on '63.
Steering System:
Recirculating ball steering. Power steering was an option.
Seat Belts:
Lap belts were optional or standard depending on build date/market. Shoulder belts were not available.
Chassis Design:
Body-on-frame construction with a separate ladder frame chassis for rigidity and crash protection.
Radio Options 1963:
