The real Cobra R has a 99/01 Cobra front bumper, the air damn is removable. FRPP sells the "real" part - they used to sell the Cobra facia kit, but now they dont, just the parts individually (costs a bit more ).
Silvr04GT: I like both combo's! The 03/04 hood might look more "unique" with that bumper, as its not as common of a combo, while the R hood would look kickass (cuz they all are!) no matter what.
