This is the "large" nut is for locking down the pinion bearing inside the axle.   It is not the smaller "flange" nut at the front of the propshaft flange.  Also, this is not suitable for any Viva HA  (inc van)  or  Viva  HB 1159cc or Viva HC 1256cc axles which use a much smaller special nut.

* Important :  Later OHC axles on models such as Magnum / Firenza 1800/2300  / Panther Lima etc axles did not use this nut.
