Thanks for you response guys, after taking measurements today, the trans angle is 6 degrees down, then the first drive shaft is 4 degrees down which is a 2 degree actual intersection. The second shaft is also 4 degrees down, and finally the differential pinion angle is 8 degrees down. This brings the pinion to a 4 degree intersection. The reason for asking, is that this axle could have been swapped out before I bought it and I'm looking for the correct factory angles.
The other factor is that the slip joint splines are badly worn and needing replacement. Would it be an advantage to putting a one piece driveshaft at this point.
