I ordered what I thought was the oem spoiler for the the 2008 G37S coupe, but the body shop I took it to for installation said that it would not fit flush against the trunk. So is the part number K6030-JLXXB the correct one for the 2008? If not, does anyone know the part number for the 2008? Also, if it is the correct part number and the body shop is wrong, does anyone know of a body shop in Chicago that has experience installing the spoiler? Thanks in advance for any assistance.
