I have an 89 YJ with an AC unit that is to say the least not needed and unused. I pop the top first chance and put it back after I start getting funny looks when I head for the woods in my fall camoes. Question is how hard is the ac unit to remove and can someone direct me to anything that has been published on the how-to as well as converting the compressor so it can be used to air tires, etc. Thanks in advance
