I have just purchased a 66 FHC which I am restoring from the ground up. I want to put air conditioning in the car but don't want to spoil the classic looks of the Series 1 by putting the ugly air vent system Jaguar created for late Series 1 and the Series 2 cars. Does anyone make an installation which is really discreet or, even better, almost invisible? I am thinking that something like the small round vents that old Sting Rays had could be integrated very well.
