i recently removed the grille on my 96 gt, and notticed the 2 air bag impact sensors are now exposed to any stray debris that might get shot up there on the highway. anyone think that a small rock could set off my airbags if it hit one of those sensors? or can they withstand a lot more, i mean I figure they are built to go off for a lot more than a pebble...just want to be sure? if not i can put a couple light brackets in front. thanks!
