How do you change the headlamp in a 92 Toyota pick-up?

On the 93 the two top screws are are visable and easy to remove. To get at the two botom onea you have to remove/loosen some of the plastic grill. Then just unplug and reinstall.

New but related question

How do I get the grill off? I can get the top clips off, but I can not figure out the bottom ones. This is on a 90 actually.
