Would a 2002-2008 Mazda 6 manual transmission fit in a 1996 Mercury Sable Wagon?

I have a 1996 Mercury Sable Wagon with an automatic transmission on its last leg. The car has a 3.0 L Duratec 30 (Mazda AJ) which was widely used in both Ford and Mazda powertrains. So here's the question, would a 2002-2008 Mazda 6 manual transmission be transferable to my 1996 Mercury Sable Wagon? My main concern is that all the hardware line's up and the drive shaft is the right radius. I choose this car because they were pretty avidly fitted with manual transmissions; meaning it would be easy for me to find a salvaged model. However this powertrain was also found in other models such as the 2004-2007 Jaguar S-type and the 1989-1999 Mazda MPV so if the Mazda 6 manual doesn't have compatible mounts is their any other car I could find a manual transmission that would fit in my 1996 Mercury Sable?
