For those of you with a TR4 who would like to direct air to your legs during the hot summer months, try the following suggestion.
Using eyeball air vents that one sees in aircraft (google Aircraft Spruce and Specialties for part number 13-01943) mounted on the bottom of the square air ducts that feed the vents on either side of the dash you can direct air to the footwell area. You'll need to use a hole saw and electric drill. When you open the scuttle vent air will flow to the dash vents and the foot well vents; the rate of flow to the footwell area is regulated by how open the dash vents are.
