1964, 1965, or 1966 Mustang Air Conditioning

Model Specific Perfect Fit ELITE™

A/C, Heat and Defrost. For non factory air & factory air vehicles.

This model specific Perfect Fit ELITE™ system allows you to retrofit an original, standard, 1964-66 Mustang with full air-conditioning. Our system is engineered specifically to use the original 1964-66 Mustang heater controls using our simple EZ Cable integrators and EZ Wire system. The new fully electricPerfect Fit ELITE™ system uses our ECU to allow infinite adjustability over all modes, providing you with powerful air conditioning, heat on the floor, and dehumidified defrost. The air conditioning and defrost connect to the original heater-defrost diffusers.

Installation's a Breeze!

The 1964-66 Mustang Perfect Fit ELITE™ air conditioning system is designed specifically to bolt into your 1964-66 Mustang with minimum modification to your vehicle. Each kit comes with detailed, easy-to-follow installation instructions and mounting template.

Not Just Aftermarket Air Conditioning!

Classic Auto Air's Perfect Fit ELITE™ model specific systems are not your typical, one-size-fits-all, low-quality, aftermarket air conditioning system. Every component was chosen for its superior design and quality rather than a low cost. Our RETROFIT designs give OE quality combined with better than original performance and reliability.

The Perfect Fit ELITE™ 1964-66 Mustang air conditioning system is engineered to actually fit a 1964-66 Mustang. not a single unit that is adapted to fit a whole product line like competitors. It comes equipped with carefully sized, large, separate A/C and Heat coils just like factory (OE) systems, not combined A/C/Heat coils often found on aftermarket systems. By using separate coils we improve the cooling and heating capacity of the total system. This makes you cooler much faster!

Want to Customize Your Solution?

Our standard Perfect Fit™ is the perfect solution for most of our customers, but we've helped many customers develop custom solutions, from hose placements, to smooth firewalls, to you-name-it, to create a personalized air conditioning solution that's just right for them. Want to pimp your ride? Don't just order the standard kit. Give us a call and let us help you customize your solution.
