When removing the old carpet, be careful not to rip out any wires glued to the bottom of the old carpet. Come up with a good way of securing the drivers footwell carpet to the floor. Cheap carpet kits will move around and could bunch up under the pedals. Be prepared to clean up any rust you find around the floor plugs and behind the seats. Whenever I get the chance, I make new circles out of sheet metal and weld them in where the plugs were. After that, apply some seam sealer to clean it all up. You will need to remove the seats, center consul/shifter, kick panels and maybe the panel behind the seats. If your lucky and your car still has them, the seat belt holders and the black floor plates under the front of the seats next to the tunnel, and the plastic pieces near your shoulder that cover the folding top mechanism come out too.
