If you just need the bottom section of the c-channels in front of the door openings, you really don't need them at all. You can simply screw that portion of the rubber in place with small black self-tapping screws through the rubber. The screw heads nearly disappear. You can put your kick panels on now and just screw the rubber on through the edge of the panels and into the inner cowl panel later.
