    Cold air is the way to go in Texas during the summer.  I will try to take some shots of Steve's install on my car.

    Steve is right about the are where you live, and the car! Convertibles have a great big fresh air vent when the top is down.
     I eliminated both left and right vents with my CAA install. The right one had to go as per install instructions, the left one mostly because of lack of real estate for all the AC outlet hoses and the EPAS install.
     Before AC the vents sure were a bonus but I do not miss them since I got cold air.

    That's good to know.

    I hate AC. I love fresh air. Fresh air at my feet when I have the window or vent window open is important to me. I went the extra steps and nabbed 67 correct AC vents so I could still have the footwell fresh air vent as the factory installed. 
    I would miss my drivers side fresh air vent large time.

    You need a convertable Gary. You can run the AC or the heater with the top down.

    Doug, 
    I have had 3 convertibles in my life and only one had A/C. I have been known to drive with the top down and the A/C on. 
    Never again. My 86 GT Vert was, and will be, the last convertible I own.

    Wife tells me to "Never say never"

    I will say, if you get stuck in the rain in a drop top in hot weather AC comes in quite handy.  My uncle had a '66 Chevelle convert that had AC (and almost every other option offered in '66, plus it was an SS396 car).  The AC does a far better job of keeping the windows clear than the defroster/defogger.  The trick is being able to remove the humidity from the air.  A lot of new cars actually use the AC for this instead of the heater I've noticed.

    Ford used a/c compressor for all settings except vent. 

    Even the blend selection used the compressor.
    I know it was on friend’s 97 f150...new body style at the time. Vent was only time compressor was not used.
    So much for fuel efficiency.

    Al’s AC valve on 65 with Vintage Air using the 5/8” foxbody hose between lower port and valve.

    MS and BobE.

    I noticed there is a difference to the heater core.
    Intake manifold should go to which heater connection?

    Below are from the Vintage Air instructions I received. The valve stops flow thru the heater core so the core should not get "warm' with it installed on either the inlet or outlet.  However, with the valve connected on the inlet, I believe, it would better stop convection from occurring thru the heater hose.  This may make the A/C unit to have to work a little harder to overcome any 'heat' contained in the heater core.

    Like Bob said, pressurized side of the core gets the valve. Same hose that goes to intake manifold, and to the lowest port on the heater core.

    There is an discrepancy here, below is taken from the 1966 Ford Shop Manual.  It clear shows the inlet (intake manifold) going to the lower heater core tube.  The Vintage Air instructions show the inlet going to the upper tube.
    I installed it per Vintage Air instructions and have had no issues with the A/C functioning very well.

    I too installed just like VA said to do and love my new AC. Just want to reroute the hoses when I do my rebuild this fall.

    Slammed Big Blue, ran over the varmints that messed with the Stang. Now all is good in the NW
