will fenders for a 02 cavalier fit right onto an 05? will there be any corner brackets i will need to buy or will it just replace the stock one exactly?

I have 00-02 z fenders on mine and they bolted right up u c the headlights all bolt to the rad core and really only the bumper bolts to it to keep the little flap thing behind the headlamp on the bumper from poten. bowing since theres no support holes i made a bracket for it litttle detail thing i feel i needed. my friend has used fenders on his 03 from 95-05 during his projects the bumper and lamps were changed to accomplish the style change yet the fender stayed the same.
