I have been contemplating building a mustang with a 12v Cummins motor. I am wondering if it has been done before, anybody ever seen it? I have read about a sn95 car with a DMax, but I am thinking a Fox body with the Cummins. I would prefer a common rail, but i don't want to deal with all the wiring. I am thinking I would have to back it with a Dodge tranny, unless there is such a thing as a custom bell housing. Any thoughts, or am I just loosing my mind here?
