Land Rover was very inconsistent in their use of 36 & 48 spline steering columns. We recommend removing the steering wheel and counting the splines for guaranteed fitment. The below is for guidance only:

48 spline bosses were used on Defenders from 1993- 1998 or base spec vehicles from 1998-2008 and any Defenders from 2008 onwards. 48 spline boss will NOT fit County specification and all XS specification vehicles from 1998 to 2007. Will also NOT fit earlier Defenders from launch date up to 1993 regardless of interior spec.

For all options where a 48 spline boss will not fit purchase our 36 spline boss

As well as early models the 48 Spline Boss will also universally fit all post 2015 Defender. The boss has been cleverly designed with a slot to accommodate the revised indicator cancellation set up.
