Civic and CRX fenders are different, despite what that website says. On Civics there is a filler panel under the headlight that runs into the fender, CRXs don't have that. Also the Civic corner lamps are trangular (kind of, for lack of a better description) and CRX corner lamps are almost an angled square. See?

The numbers on http://www.hondaautomotiveparts.com/ aren't Honda's part numbers, it's their own. I'm sure the number refers to any fender.
