Front license plate bracket removal?

I have a 96 blazer and am wanting to remove the ugly front license plate bracket to make room for some driving lights. There are two push pins in the front that are easy enough, but then there are two large metal screws that appear to be installed from inside the bumper..WTH? In other words, you can only see the bottom studs of the screws hanging down, I can't even feel the tops of the screws inside the bumper. I guess I could cut the bracket apart while on the truck until I could get vise grips on the studs of the screws and back them out from underneath, but I was wondering if there was a better way...Thanks!

Thing was taunting me last night, so it got the buisness end of a sharp pair of 6" diagonal pliers. Worked great, got the whole thing off.
