Anyone know where to find an HVAC vacuum line diagram for the early Foxes? I can only find 1960s and aero cars (87-93) via Google images and my Haynes manual does not have a good diagram. I took the dash on my '86 apart last night to see fi they are the same, but they aren't. It may be close enough to figure out, but if I had a diagram I'd feel better than just winging it until I get it right.
