if you're talking about the rocker panel, it's quite easy i just took mine off last week and i should've done it a long time ago. there are 2 bolts and nuts on each side, 1 in front and 1 in back that you have to get from underneath the car kinda by the wheelwells. just look or feel where the panel ends and theres a bolt sticking through the backside you have to take the nut off. once you get both nuts off the panel will need to be slid off the brackets holding it on. start on one side and you kind of have to pull up on it to clear the top lip, then push down to get it completely off the clip. i believe there are 4 or 5 clips on each side. once you get the actual panel off you will see that the clips holding it on are butt ugly and you'll want to get them off too. unfortunately they are riveted on and into the lower metal of the car. the rivets need to be drilled out, 2 on each clip, and then the clip will come off with minimal prying. there are 'holes' there from where the clips were and it might be a different coor depending on the previous bodywork. most people weld in new metal over the holes and then smooth it over.
