Hi. I have done this some time ago, and I don't have the car here to go out and look to refresh my memory. So here is what I remember. The black plastic under-piece separates from the carpeted part, which I believe I left in place. It all comes apart with screws, and there's one down near the brake pedal. It wasn't too pleasant, 'cause I had to lay on my back with a light to find the screws, head wedged next to brake pedal. Good luck!!
