Product Description

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, 1971 Ford Mustang with full air-conditioning. Our system is engineered specifically to use the original 1971 Ford Mustang heater or air conditioning 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 supplied heater-defrost diffusers.

Installation’s a Breeze!

The 1971 Ford Mustang Perfect Fit ELITE™ air conditioning system is designed specifically to bolt into your 1971 Ford 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™ 1971 Ford Mustang air conditioning system is engineered to actually fit a 1971 Ford 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!

A Case for Quality: Even Classic Auto Air evaporator cases put the “competition” to shame. These cases are made from high-impact ABS and vacuum formed with an even temperature to produce a stronger case with uniform thickness and a smoother finish. Also, these evaporator cases are fully insulated… another Classic Auto Air exclusive!

Condensers: Classic Auto Air 

utilizes custom made state of

the art parallel flow “micro tube”

condensers. These designs are

used today on modern vehicles

to reduce head pressures and

to transfer heat more efficiently.

With dozens of custom sizes and shapes available we

tailor fit each one to your specific vehicle, making it a “Perfect Fit.”

History: When you buy a Classic Auto Air system you are getting 37 years of real world, high-tech, cooling technology. You can’t beat experience!


For your 1971-73 Mustang we also offer our EXCLUSIVE Direct Electronic Replacement controls (D.E.R.)… which gives you a brand new, plug-n-play control that fits right into the OEM location with no modifications! (Included in kits for factory air vehicles)
