I think I wasn't very clear with my question. I was asking is anyone hasn't changed the out put shafts on the LST diffs and ran them with LST axles like you did on your Revo. I know that the bulk heads have to be shaved in a few areas from your post and from when I did mine to make them fit. I guess I still might not be very clear on what I am trying to say. Keep the LST diffs stock shave them on the top to clear the chassis, but build the bulkheads around them. If you keep the LST diffs stock they wont fit through the slots cut like the stock ones do. You would not be able to get your diff out without taking your bulkheads apart but you also would have to swap the stubs over inside the diff. This was something I was kicking around and was curious if anyone else has done it or thought about doing it this way.
