Eddie at West Coast Rovers is handling the sales and distribution of Safari Gard stuff... Give him a call.
Depending on how you are going to use the truck, you are better off with RoverTym or Safari gard stuff. The ARB is a cheese grader, it has absolutely no approach angle.
Custom fab is also a good option, there are several fab shops out there that can build you something to spec for about the same price as an off the shelf model.
