Ideas Needed:How Can I Fix This?

[240SX21]

hey guys. ok im in the process of putting on a body kit & getting a paint job on my 89 240 but i ran into a problem with the front bumper. the only way i could get it to fit properly was by screwing it in a couple inches lower than the stock bumper position. which means that i now have a 2 inch gap in between my bumper & hood/lights. i posted a pic below. any ideas on how i can seal this gap? ive heard several suggestions, including using fiberglass resin to seal it or putting mesh in the gap(which is definetly out because i want something solid there, to prevent water from entering & also to prevent someone from reaching into my engine). im still considering my options so i figure if anyone can help me its you guys. any & all ideas are appreciated, thanks!
