the tread part of the dead pedal pops up and flips over to one side. Its held together though with that black sticky stuff and is a PITA to move. after that is flipped over you will have access to the bolts holding it to the car.
I have put on just about everything from a GL to my Loyale including the dead pedal, map light, door handles, rear cargo light, etc... All of the factory holes are on the car just under the plastic or headliner. For the map light and rear cargo light make sure to grab the wire with the plug from the donor car, just unplug it from the donor and plug it in the Loyale. The Loyale harness has the spots to plug in the lights so no need to monkey rig some more wiring. The dead pedal and door handles have the mounting points also just like Numchux mentioned. Just make sure to get the hardware off of the donor car so you can just bolt it right up to your Loyale. I can post pics sometime if people need it.
