    The assembly is held in by four bolts that go through tabs in each corner of the headlamp assembly.  You have to take the grille off first, to get at the tabs, and the little cover plate between the grille and the core support (radiator).  This is just a matter of taking out bolts until you can get it off, and then remembering where they all went when you put it back together.  It's so easy and obvious that I doubt if anyone even prints step-by-step instructions.  If you can do any of the other work on the truck, you should be able to do this.  Put two new bulbs in it before you install it, it will save a lot of trouble later.
