where does your big ricey one mount right now? if you dont get a spoiler that matches the mounting holes you already have, you're gonna have to fill those and repaint the trunk lid. after all that work, i'd just leave it wingless.
i had the oem spoiler on my 95 teg 2dr. i liked it. but i also like that flush mount style as well. if i were in your shoes, though, i'd just take the shitty wing off, fill the holes, paint it and call it a day.
