Is it out of a Dakota or Durango? If so The 6x4.5 bolt pattern is an odd ball pattern and I don't think there is a lot of aftermarket support for it. Not would it be easy to make the front axle match that pattern. Regardless, it sounds like it needs a fair bit of work and money put into it if you don't have the knowledge and/or tools to set up the gears properly. If it were me I would pass and find a more common axle that requires less work.
