Adding Air Conditioning to 07 yaris

[BCbenny]

I have a base model 07 sedan yaris. I enquired with toyota about six months ago about an a/c kit (the dealer in victoria B.C.) which they were showing a part number for at the time. I didn't get it when I called but now they are saying it's not available. I have the ability to install a kit and could probably scour around to make my own but it's so much easier to just buy a kit so does anybody have any online sources which may still be able to provide a complete installation kit? Or maybe they can still get a kit for an 08 that might work for an 07? Anyone with any info is helpful (unless the info is something along the lines of "save yourself 1000$ and roll your windows down..." my wife wants a/c, she'll get a/c)
