Yeah Dave, it'll be a direct swap since it's a small case e30 diff. You won't need to swap the cover or halfshafts, but you may need to swap the output flanges if the bolt pattern doesn't match your current halfshafts. The output flanges pop right out, no tools required other than a wrench or screwdriver to pry them out of the case with. Just use a sharp jerking motion and they'll come out, but again, you might not need to if the bolt pattern matches. Is your car an automatic? If so, 4.10 will nicely lower the rpms to a comfortable range @ highway speeds.
