4WD units are mounted between the primary transmission & transfer case; installation on Ford single cab 4 x4 vehicles with dual fuel tanks will require modification of front tank. Also, Ford Crew-Cab models will require modification to floor pan to make the necessary clearance for the Dual Range and the new location of the transfer case.  This can normally be accomplished by pushing up on the floor.  Contact your dealer for more details on your application.
