Most sites show that the early auto iX's had 3.73 final drives. Here is one front from an early auto car.


With that said... Good luck finding a viscous rear.
Any chance you could take a us spec V3.91 or something and rebuild it using parts from a US spec 3.73S from a RWD car to make a viscous rear end to match?
