96-98 99-02 front end conversion bumper & grill
 

Hello im fairly new to 4runners. Im about to trade my integra in for a 98 limited 4x4 for a great deal. Ive been researching around and it seems that the 99-02 front ends are dfiffernt than the 96-98. they have different front bumpers and grills. i checked for parts on ebay and it seems that the headlights are different also? how hard would it be to convert my 98 front end into the factory 99-02 front end? would i need new headlights, grill, front bumper, fenders and hood? just by looking at pictures it seems like i only need to swap the front bumper and grill. i was wondering if they are all interchangeable and bolt on without any modifications needed? if anybody has experiece with this conversion and any input would be greatly appreciated thanks :)
