The suggestion that the ventilators would allow warm air to enter behind dash I believe originated with myself but I would not go so far as to say we should not fit ventilators to cars going abroad. Rather should we try fitting the ventilators higher up. Signed: R D Spring This Sheet must be filed on completion of the work. | ||
