SO why are you selling this?
Here is the short story: I originally wanted to run it in the front of my rig. Several years ago I "clocked" my front housing quite a bit to ease driveline angles. What I found is that with the front being clocked the motor on the unit interfears big time with the spring pad creating another mess to deal with. So then I decided to run it in the rear until a friend of mine decided to sell his D-60 6 lug.
So: I no longer need it or can use it. :-)
