1982 alfetta gtv air con drain hose

[marktim]

Well I've been lucky enough that my air conditioning is now working and has been re gassed and is working ok, the guy who re gassed it couldn't believe how much gas my system took, he said a car of this size usually takes around 300, 350  but mine took over 700,he said the compressor is an American model usually on bigger cars, go figure, anyway my question is where is the drain hose on these cars, I've looked and can't see it mind you my eyes aren't what they used to be, thanks for any replies, cheers.
