I went back and forth on this for a long time. I'll be using a universal evaporator since all my lines will enter the car in the wheel well. I like the idea of having electronic controls because it reduces the amount of knobs from 4 to 3. The vintage air electronic evaporator is huge and I was worried about it taking up too much real estate under the dash. Some smaller electronic options are Classic auto air and Restomod Air. The price starts getting crazy on those brands ($1000), not to mention the $350+ controller. A friend had the Vintage Air Gen II super empty fitment box so I gave it a try. It's small, but needs the 4 knob controller. Once I saw the price (~$500), I figured I could get over having an extra knob and go with the Gen II. I'm going to make something to mount along the bottom side of the dash to house the louvers and controls. I have a few ideas in my head, just need to turn them into sheet metal.
