I recently came across another commercially available wrap-around brush bar for the 4.0/4.6. This appears to be stronger than the factory brush bar, as it is an all-steel design made of heavy gauge tubing. It incorporates headlight guards (see photo at right), and the center section extends downwards for strong attachment to the lower chassis crossmember and protection of the lower radiator area.

This bar, available through Atlantic British, only costs $569 -- a record low in my experience of other Range Rover P38 accessories!!
