I am looking to replace the front bumper on my 2000 GS, but I'm just wondering, if I can't find another GS bumper that matches, would a GS or GTS bumper fit on my car? Or how about different 3G model years?
You can facelift swap to the round fog light style. Not sure how. You can just get a cheap plastic replacement from eBay with free shipping and have a local shop paint it. I have both styles of vents. Don't bother asking anyone here to ship you a bumper, they are expensive to ship and not worth it. The fog lights have different pigtails and I have thoes as well.
All bumpers are direct fit. RS/GS/GT/GTS. The only difference in bumpers are from 00-02 and 03-05. They have different fog lights, bumper inserts, and turn signals. If you switch to a different style, you'll have to replace those parts and possibly extending fog light wiring.
