Atlantic British Ltd. - Largest Independent Supplier of Parts & Accessories for Land Rovers

Before the side sliders can be mounted to the sills and outriggers, the mounting arms must first be bolted to the main slider using the 12 x 20mm bolts supplied.  The arms can be adjusted left and right for a better fit. 

Remove the original sills, enlarge the holes in the sills to allow a tight fit of the riv-nuts. The replacement sills (rocksliders) are mounted using these sill holes and riv-nuts as well as the chassis mounting bars. 

The shallow angle mounting brackets x 2 (figure 1) are used on the rear vehicle outriggers.
