Holo From the Blizzard Belt of the Rockies Our '66 has the dual A/C option. but I have a problem using the rear air since the hosing is in-complete. It is rigged so that only the front unit is connected. The two hoses for the rear are connected to the hard lines at the firewall and just dangle upward into the engine bay. Do any of you have a photo of the routings and of the connections ???? Or have the ability to explain it in very simple terms so that one may "paint" a mentle picture ??? Due to the weather I don't want to use the air at this time. But in about a month I'll be thinking about reaching for that switch. Rodger & Gabby Colo Spgs '47 De Soto Custom '63 Le Baron '66 Le Baron
