996 GT Trim Rear Diffusers - install question

[chriseldorado]

I have a set of used 996 GT Rear Trim diffusers parts numbers;

996 505 977 00

996 505 978 00

They have about 6 screw mounts that lead me to believe that there is a bracket that accompanies the diffusers to be mounted on the inside of the lower rear bumper. Has anybody installed these that can confirm what the brackets look like or if they simply mount to the existing bumper moulding? I am a little leary about mounting these to the bumper with, say, epoxy because at speed, they I am not sure if they would actually pull the plastic bumper away from its mount points.

thanks

The Porsche TSB that describes how to install the GT Rear Side Skirts says the kit has templates for drilling and mounting the side skirts with the screws. No epoxy.
