You are right the upper grille for the 91-93 has the thicker bars. I would take $50 for it. The spoiler was originally off a Nissan altima. I don't have any pics of it but it is very similiar to the G20T wing except it goes at more of an angle.
NOTE: The color is not the same as your car, it is the pearl white that almost looks cream. It's the color of AF member DJHotpockit's G20
