AC Car.. Drop In or Piece it Together AC System
I just bought a Gen IV evaporator and inside cabin kit for a 55 Chevy or something because Summit had it of sale for 25% off. I installed this in a 57 Dodge pickup I'm building. The rest of the components including the triple pass(R-134 requirement) condenser and receiver dryer I bought from Nostalgic Air, and the 99 5.9 Magnum based engine had a Sanden Compressor driven by the factory serpentine belt.
I had to fabricate a few simple sheet metal brackets, but it's pretty simple without requiring a specific model kit.
I did the same thing years ago for my 68 Barracuda because there were no kits for that either at the time. Any hydraulic hose repair shop can crimp the lines.
The biggest key for a comfortable cabin is to insulate the interior using a Dynamat type product to dampen any panel resonation in conjunction with a double foil sided jute insulating blanket. I cut a dozen or more panels (like a seamstress makes clothing) and fit that into the cabin from windshield to rear window, behind the door panels and even under the headliner. I then use aluminum duct tape to seal the seams and secure the edges covering as much of the interior as possible.
The results in my '70 E-Body are stunning. When the door closes, it sound like I'm in a bank vault. Pictures are of my A-Body too.
