Hello, my friend has a 2002 Civic with damage to the door, bumper, and hood. I would like to know if it is possible to swap 2004 versions of those, plus headlights. And also would like to know of places to get doors for these. Thank you in advance.

This is not a direct swap. You will need the hood, fenders, bumper, headlights and harnesses. This is expensive and NOT worth it at all. If you were to waste this kind of money you might as well do a RSX conversion.
