I have a '97 Civic and the bolt holding the license plate was siezed
to the nut inside of the front bumper.

In trying to loosen the bolt, the nut in the bumper came loose and now
I think I'll have to remove the front bumper to get to the nut on the
backside. I can't see how I can drill it out if I can't get a grip on
the nut in the back.

Is is very easy to get the front bumper off? The tech manual I have
seems to make it look easy. How do I deal with the foam inside? (Cut
it away?)

Thanks in advance for any help. BTW, I am pretty much a novice when
it come to cars.
