* A complete A/C system: This includes the compressor, condenser, evaporator, drier, hoses, lines, and all related components. Finding a system designed specifically for a '77 Corvette would be ideal, but adapting a system from another vehicle might be necessary.
* Fabrication and modification: You'll likely need to fabricate brackets and modify existing components to accommodate the new A/C system. This often involves drilling holes and making other permanent changes to the car's structure.
* Professional installation: Unless you have extensive automotive experience, including HVAC system installation, it's highly recommended to hire a professional mechanic specializing in classic car restoration. Improper installation can lead to leaks, poor performance, and even damage to other parts of the car.
* Electrical work: You'll need to wire the A/C system correctly and potentially add additional electrical components, including relays and possibly a larger alternator if the existing one is insufficient.
* Cost: Expect a significant financial investment. The cost of parts, labor, and any necessary modifications can easily reach several thousand dollars.
In short, while it's doable, it's a complex and expensive project best left to experienced professionals. Researching specialized Corvette restoration shops in your area is highly advisable before attempting this.
