it has been done before but i dint think its practical.. that stud for locating the axle fer one thing. you could turn them upside down then yer diff drain and vent would be in the wrong place etc etc
Then your diff would be pointing the wrong way, so you would have to modiffy your prop with the aid of sum elabrate brackatary in order for it to work.
Sounds like alot of work for not too much benifit. i think i will stare at her till i come up with another silly idea.
if yer diff is facing the rear, just turn the axle round so that the o/s becomes the n/s etc etc, swap the vent for the drain plug and robert is yer mothers brother as they say
