Review on InterDynamics Certified AC Pro Car Air Conditioner Adapter Kit (4-Piece Set) - R12 to R134A Refrigerant Conversion, High and Low Side Ports, VA-LH11 by Will Micheals

Did its job perfectly. Replacing my sons 89 Chevy C-1500 A/C with R-134A. worked fine It's been blowing cold for 6 weeks now. Very happy with this kit. Just make sure you have the new Schrader valves (the right ones). The high side is unique. 8 ounces of PAG oil in a clean system and you blow stone cold. Standard cabin too. 36 ounces. freon. I blew 45 degrees when I did it. It also included a new A/C compressor, throttle tube and battery. Cute!
