Hi Jake.
Yeah you need to remove the entire plate surround which has some plastic clip type things. There's four of them in total. Just pop the grill off and you can get to everywhere you need to.
Yes it does mean drilling some holes, just do it carefully and take your time aligning them. I just used some very small screws with washers, and lock thread nuts.
It bends to the shape of the grill no problem.
Andy.
