I have a line on a 1966 fairlane with a 390 motor and auto tranny, but the only way i would be interested is if the tranny is a C-6. I am going to swap the tranny and engine into my 1978 ford truck if the tranny is a C-6. when did ford start making the C-6, and how could I tell if this car has that tranny? I can't crawl underneath it because it is about an hour away from me, just trying to see if this swap is even feasable before I make the drive up there to look at it or drive it. Thanks, Ben
