This is the air conditioning evaporator for your 1982-86 Mustang LX or GT. It is located under your dash and it's job is to pull heat from the air blowing into your car to produce cold air flow inside the cab. This car can become cracked over time and may need to be replaced. This is a direct fit factory replacement for your Mustang!
I've done the majority of my aftermarket mustang parts shopping at American muscle, recently finding out about this website I'd just like to say it is a great experience to shop here, the lay out is easy and simple to navigate, and you have thousands of parts that no other website has. The shipping is very fast and all te updates are great. I will be doin much more shopping with y'all, so thanks for being so badass haha
