Pictures from Gerry Holland of his ventilation setup. To quote,
"I modified the Ventilation set up using parts from Glastar Accessories provider - Airlink Technologies.
I've used Aluminium Eye Ball vents and positioned them so they are above knee and thigh positions when in normal seated position."
