2007 Rear Bumper Conversion

[Localbrew]

I'm about to do the rear bumper facelift to the 2012 LCI bumper.

I know I need the following:
1. rear cover
2. left and right lower pieces
3. center difuser
4. center lower trim piece
5. reflectors left and right
6. anything else?

Are there any mounting brackets that are needed? Has anyone done this I'd like to get their input if they have. I know I need to remove the rear fender flares to get access to the side panels.

Would love to get any help here, and yes I have searched and searched.

Thanks,
