Dave,
Would the Old Air unit fit under the seat?
I've been thinking of putting some louvers in the front of my '50's seat skirt with a big-ole AC unit under the seat but I haven't come up with a system yet- I hate the look of the aftermarket vents. and I don't like air blowing onto my face anyway. A cold seat would be ideal, with air flowing from the floor of the cab up behind the seat and blowing out onto my neck.
