04 corolla--Need help installing new headlights

I have a 2004 corolla s. I just purchased some new halo projector headlights for it and am trying to figure out how to install them. There is a bolt that seems unreachable by any normal tool. I was just wondering what the easiest way to reach it might be without having to take off the quarter panel or the front bumber (which seems to me to be the only way to get at it). Any help wouldbe greatly appreciated...

i'm pretty sure you're going to have to loosen the front bumper to get to it. don't quote me on it, but i'm pretty sure thats what my buddy had to do when he changed his 03 headlights

yep you will have to remove the bumper but it takes less than five minutes and just as much to put it back on. all you have to do it remove the bolts on top under on the sides and the mid-upper clips be careful not to break them.
