It has a captive nut inside the foot well, I had mine go on me so I peeled back the carpet and started to peel the sound proofing away witch leaves a recess and hopefully the solution to the problem(as far as I can remember there was not any cutting involved but spuddy has the right idea of refrencing the point to cut and dont worry inside the foot well isnt going to affect the structure of your car as long as u don't cut it all out ) . Now I did this on my 82 in the drivers foot well. what I'm saying is its not the end of the world so don't despair......
