if your not willing to take the box down and check first hand im not sure what you want other people todo ! apart from take guesses like i did.. youve done alot of reshreach and come up with nothing would you rather order the wrong diff to find out it dont fit ! then send it back (more money ) incure a surchage (more money) to get the correct one !
its not as if you can use the car in this day and age ! (lockdown)
stop looking for the easy way out to put it blunt !
