Hi all. Am putting a Hot Rod air (air conditioning system) in my '46 Ford. I mistakenly thought the fittings were AN fittings. I've since learned that they stopped using AN fittings quite awhile ago. My question is (what are the new fittings called?). I have a new Sanden compressor, new condensor, etc. I understand that the fittings still come in sizes #6,#8,and 310. your help is greatly appreciated. Many Thanks.
