not going to run a/c on my maverick when I do the 5.0 swap. My parts car has a complete a/c system still on it, though I cannot gaurantee it works. It does have freon in it. I am yanking the engine and leaving the a/c still in the car so I don't have to bother evacuating the freon. If anyone has the capability to evacuate the freon, and wants the whole a/c system for free, let me know, the trick is that you've got to come to my place in Corona ca. to get it.
