Classic Auto Air Installation 74 Dart Sport
Well now on to mounting the box. The green car in the pic is a 72 Plymouth Duster non AC car, the red car is my 74 Dart Sport non AC car. The motor mounting holes are a different but the motors are the same size and the firewall hole is the same diameter.
The CAA box comes with a bracket mounted at the back to secure it to the fire wall using two 1/4 20 bolts matched up to the original motor mounting holes. I found the bolt hole in the 2 oclock position matched up with my 74. The hole at 11 o'clock did not. I simply drilled another hole in the fire wall through the CAA box bracket and secured it with a self tapping bolt. Then installed the interior support brackets up to the interior air box. The black cover plate over the AC & heater core lines comes with the kit. The box installation is done.
