Here is a link to a 2WD Ramcharger with a 6BT but the steering info applies. The centerlink will rub the oil pan on the Cummins engine so you need a centerlink from a 3/4 Ton Dodge Cummins truck. Also the 4WD transmission crossmember will work better with mounting the NV4500 or Getrag G360 transmission. Other than that it looks somewhat easy. I have this same project on my list of things to do provided I live long enough!
