No barge, we went over this. running a rear diff up front doesnt make it run backward, it just changes the drive side of the ring gear to the coast and coast side to the drive. you still get forward movement when put in drive though. put a IRS diff up front and call it done.Yes, but then shits spinning backwards. Same issue with trying to run a rear diff, ring gear ends up being on the wrong side.
im surprised that the diff cover upside down works correctly. both low and high pinion 8.8 have the pinion off set to the left of the ring gear when looking from the rear to the front unless where the ports are, are on the bottom/top of the cover?
