There might be some cutting and/or filling involved there, but I would go find a prelude and measure the taillights, see what mods will be required. I really think the 90 Legend taillights are a better bet, easy bolt on and they look great.
Everytime I see the latest gen prelude with those lights I think, woah, Legend Tail-light design...I'm like finally Honda got the styling right on one of the new cars!.. then I see the front of the new Lude, and think.. wtf where they thinkin'??
