I have a 73 GT with A/C. It has the dealer installed ARA system. I am wondering what was the original air cleaner arrangement. My car has the A/C compressor located on the passenger side of the engine. On a non A/C GT, this is where the air cleaner box sits. The car has always had a Weber with an air cleaner right on top of the carburetor. Is this original for an A/C car? Did the dealers here in the US change out the Solex’s or was that always done by the owners? Any help?????
