Luke, I'm not sure if you'd like to remove and replace, or permanently remove the trim.
The lower body trim is held in place with plastic clips all the way except at the door edges where screws are used. You'll have to open the hood and reach in from behind the trim alongside the headlights to remove the nuts holding these on. You could also gain acess by removing the outer headlight bezels.
If you're looking to leave everything off, you'll have to break off, then grind the weld-on studs holding each clip and fill the holes at the door edges. Of course this will also involve paint work.
Hope this answers your question,
Rich
