I think I want to put an AC in the 4 door or perhaps the coupe I am picking up soon. But I have a couple of questions. I have the Sanden compressor and a condensor in my garage. How hard, or is it even possible to rebuild it? Also what can I use for a main dash unit. I know that Classic Auto Air sells kits for the under dash systems. But does anyone make an AC only hidden style? Sherman Gossett
