If you look closely at the left taillight of his SS, it goes "Amber, Red, White" ... on american versions, itll go "Red", then White on top of an Amber (for 97-02 models). The IROC's looks almost inverted in colors, like Amber being on the outside instead of red.
*EDIT* BTW, if you come across another pair of those SS export taillights as well, ill hook a brother up with some $$$
