It is really an easy job to fit, comes with 4 screws top cushion mounts to the black plastic edge protector which is removed to do the fitting and the bottom cushion just fits into place and then is also screwed in with 2 screws from the bottom. It is a BMW part so it is designed to fit. There are two holes you need to drill in the plastic piece for the top cushion but there are two little markers that are screaming at you saying "drill here !"
I put some black silicon in with the screws just to hold them in place.
10min job and worth the price.
As nadeem however says, don't put the box down on a rough surface.
