hood is aftermarket. the lower front bumper valance is oem found on daytona/rumble bee/hemi sport and is still available brand new (primered only) from the dealer and maybe some ebay sellers. You definitely need the hardware kit for the valance I know from experience both on my 02 and 06. The valance only works on the sport bumpers (all painted like the one you added a pic of)
Make sure the chin spoiler is for your year, there have been horror stories of people getting mismatched years and they are NOT interchangeable between 02-05 and 06-08 and like he said, make damn sure you get the hardware kit as that's the only thing that holds it up.
