🛡️ Safety Features

Safety Ratings Era:

Modern safety ratings (NHTSA, IIHS) are not applicable to 1963 vehicles. Focus was on structural integrity and driver control.

Brakes Type:

Four-wheel hydraulic drum brakes standard. Optional power brakes. Disc brakes (front) became standard on all Corvettes in 1965.

Steering Type:

Recirculating ball steering box. Power steering was optional.

Seat Belts:

Optional equipment, not standard on all models.

Rollover Protection:

No specific rollover protection structure as found in modern vehicles. Convertible models have limited protection.

💡 Technology Features

Radio:

AM radio standard, FM stereo optional. Basic analog tuning.

Cruise Control:

Not available on 1963 models.

Anti Lock Brakes:

Not available.

Bluetooth Usb:

Not applicable.

🔧 Maintenance

Engine Oil Change Interval:

Typically every 3,000 miles or 3 months, as per contemporary recommendations. Modern synthetic oils may allow extended intervals, but original specifications should be followed for historical accuracy.

Transmission Fluid Change Interval:

Every 12,000 - 24,000 miles, or as specified in the manual, depending on usage.

Rear Axle Fluid Change Interval:

Every 24,000 miles, or as specified.

Engine Oil Specification:

Straight weight SAE 10W-30 or 10W-40. For older engines, specific formulations like SAE 30 might be recommended due to bearing clearances. Use of ZDDP additive is highly recommended for flat-tappet camshaft protection.

Transmission Fluid Manual:

GL-4 gear oil (e.g., 80W-90). Avoid GL-5 as it can be corrosive to yellow metals in older synchros.

Transmission Fluid Automatic:

Dexron III/Mercon (or equivalent compatible fluid for Powerglide).

Rear Axle Fluid Specification:

Hypoid gear oil, typically SAE 90 or 80W-90, potentially with a limited-slip additive if a positraction unit is installed (though less common in '63).

Brake Fluid Specification:

DOT 3 or DOT 4 hydraulic brake fluid (ensure it's a quality, modern fluid for optimal performance and seal compatibility).

Coolant Specification:

Ethylene glycol-based antifreeze with water (50/50 mix). Ensure compatibility with materials used in classic cooling systems.

Engine Wear Points:

Valve guides, piston rings, main and rod bearings due to high performance and potential for hard use.

Chassis Corrosion:

Frame and body rust, particularly in wheel wells, rocker panels, and around chassis mounts.

Electrical System Degradation:

Aging wiring insulation, corroded terminals, failing switches and relays.

Suspension Bushings:

Degradation of rubber bushings leading to loose handling and noise.

Carburetor Issues:

Vapor lock, fuel leaks, worn accelerator pumps, and sticky linkages are common with older carburetors.
