I thought it would be really easy to remove the front bumper, and it is, but there's one screw that's a total bitch

I used this site since im removing my bumper for the first time. http://www.team-integra.net/sections...ArticleID=1143

Here's the problem. It says that in front of the wheels (in the back part of the bumper, i simply have to use a philips screwdriver to remove it. but i need to use a wrench or something to remove mine, and i need to hold the top portion in place to remove it...

here's an example pic...


Must use wrench/socket-wrench to remove


Pic from the bottom...



Now you're probably thinking that its easy, and i could just use a wrench to hold the top part in place while i use a 10mm socket to remove the screw, but the wrench doesnt even fit in the top portion so there's no way to put it in a position to hold it in...

Anyone know how i would go about removing this part of the screw???
