If we can use their halfshafts, we can use their upgraded aftermarket versions and, since I personally plan on swapping to mustang bolt pattern, i can swap to 31 spline. And the centersection is similar, but the mounting methods and mounting points are entirely different. But other than that, the gears and anything important relating to the differential is the same. Apparently the axles are the same in length, which I believe to be the most important part and the ends appear similar. As long as th axle shaft doesn't rub the rear upper control arm at full compression, everything should be splendid.
