I haven't done your model truck specifically but most of them are pretty much the same. You have a bracket bolted to the frame ends and this bracket has two extensions that go to the bumper.
If you have a urethane section, that bolts to the top of the metal portion of the bumper and the bottom of a horizontal piece that runs to either side of the truck below the grille.
I'd suggest you get a service manual for your truck (usually available on CD in a .pdf format online - I got mine on eBay for $10) because the exploded view drawings, diassembly and reassembly info is priceless.
Not much is needed in the way of mechanical skills but some knowledge of how the assembly is attached to the truck is a definite plus.
