Take off the bumper and it will most likely just pop right off, if the car was buit on a good day it probally has one bead of glue down the center. If it was built on a bad day two globs of glue on each end. you should put it back on when you're done because it keeps the bumper from shaking and makin a ton of noise at high speed
Hmm well i dont see any glue holding it on, instead there are two large rivets holding it...I think im just gonna cut some of the foam to mount my ic. I dont feel like drilling them out and then installing new...at least for now.
