99 si

wat's up everyone. I got a 97 civic ex and it was sorta damaged in the front. Both fenders had grapefruit size dents, the headlights broke, and the bumper had big fat tears on the bottom. Also the grill broke off. So i bought a 99 si front end. It's all on there except for the Si grill. Only thing is, it doesn't fit very cleanly yet. I've heard that you need a 99 Si radiator support. I cut the inside of the bumper to MAKE it fit, but i can't tell until i get the grill, since it holds the bumper up. Anyone do the same modifications? Any help is appreciated.
