Thanks for the replies.
There are a few companies here that fit aftermarket A/C kits to cars (cost 1,150 pounds) however to be honest i really didn't want to leave my Saff with them

. There are 2 Saffs that have had the kits fitted and do work quiet well. I know/seen that they had removed the stock heater box and replaced it with there own heater/evaporator/fan unit and the A/C compressor was mounted under the power steering pump. I'm not to shore on the rest of the parts though.
I was hoping that the parts to convert the Saff to A/C were still available and that it would have been a matter of simply buying and fitting the parts but it seems its not as straight forward as I thought.
I think I will bite the bullet and wait till winter and then book my car in as they tend to drop there price over winter.
Yeah the weather here in Australia is a real bastard…………..Great one day and perfect the next
