There is one that some people love and hate. It is a flange that slides over the output splines, and is held on with a bolt that goes into a hole you must drill and tap in the center of the output shaft, that is why it is either loved or hated. I have heard of some people using parts of np208's in off brand trucks, but don't quite know thw particulars . /forums/images/graemlins/k5.gif
