Personally I'm into the fabrication part of the hobby so making a custom bracket for my duster or my power wagon was part of the fun. But if you're into plug and play and have the coin CVF racing has a pulley and bracket kit that will accommodate.. The 134A is a no-brainer.. I prefer the cold master 22,000 plus BTU unit over the vintage air or old air that I've helped customers install. It's the difference between yeah I can feel a little cool air and turn that damn thing down before my fingers go numb....
