[W124] Removing rear bumper

[Frank Smyth]

Hey folks
 
Is there much involved in removing the rear bumper on a W124 coupe ?  Mine looks like it's screwed in within the wheelarches, and then bolted in the rear floor area. Anything else ? Would hate to go at it and not know about a hidden slide or screw and crack the thing ;-)
 
Mine has the AMG bodykit as well, which maybe complicates things

Plan is to drill some holes in the black-plastic section for a reversing-sensor kit
