Tjkj2002, How does the SFA kit connect to the 3.7 motor mounts? Do you think that the 4.7l mounts, specifically Grand Cherokee mounts, could potentially present a problem with installing the kit? I don't believe that a problem would exist getting everything properly set up. But you can never be too sure. I haven't seen any photos detailing how everything attaches to beagle to know one way or another.
