For those of you looking for sliders for the P38...your time has arrived.

 

 
The basic design is a 2" x 6" x 1/4" wall box tube welded to are pair of custom mounts. The mounts are more or less U shaped and is held in place by a 3/4" bolt that goes through existing holes in the frame. The mounts encompass the frame at some if it's strongest points. The mounting brackets are made in such a way that they are certainly stronger than the Range Rover frame. The Box tubing sits about 1/4" under the sill and extends out to be in plane with the outer edge of the tires. The bottom of the slider is slightly below the bottom of the frame providing much needed protection for the Transfer case and exhaust system.  The overall design also provides for some additional side impact protection.

They are extremely strong and have been trail tested. You can use a jack under the sliders to raise the entire side of the Ranger Rover if you would like.
 
Our methodology was to build a slider that could be attached to the P38 Range Rover without the need for other vehicle modifications and to be strong enough to take any type of impact possible. To do this a frame mounting option had to be found with existing holes for any hardware. So, the challenge became to construct brackets in such a fashion that they could take the abuse with out damage to any other components.

The result, two brackets on each side that encompass 3 sides of the frame (all but the top) and use one 3/4" bolt to connect the side plate together, and pin the bracket to the frame. The Steel used in the brackets is all 1/4 plate, which is by far stronger than the 14-gauge sheet metal used to build the Rover frame. The actual slider it self is pretty simple.... brut strength, a 2" x 6" piece of structural box tubing is used for the slider it self. The brackets extend almost all the way out to the edge of the box tubing, and are welded on on 2 of the 4 sides.

You ask, "Where are the frame attachment point?" The forward bracket encompasses the frame where the Transmission cross member connects. The rearward bracket encompasses the frame where the rear-trailing arm bolts to the frame. Both of these points are strong structural points of the frame and are designed for high dynamic loading.

Cost:

$700 a pair with all mounting hardware

$400 Brackets only (you build the rails)

The sliders are strong enough to support the weight of the Ranger Rover at any point:

 

The design also accommodates the flex that occurs as the rubber mounts and other components flex without running into the body:

Here you can get a perspective of how Sliders extend from the sill to provide some side protect.  Conversely, the sliders do not encumber the your clearance from the side.  As you can see, they do not extend out more than the side of the body in the middle of the door:
