You won't be able to do that without cutting it and then reglueing it... remove the plastic from the shroud I mean.
You can, however, slide the bezel in from the back side and work your fingers around the bezel to push it down after you line it up inside the housing. take your time, the sticky backing of the bezel can easily get stuck to anything it touches, so make sure it is perfectly lined up before pressing the bezel down into its place.
hope this helps...its easy, just take your time and it will come out great!
