The quarter panels below the side mouldings and behind the doors are not that difficult you just need to be careful. Make sure all the pop rivets are removed - seven aluminium rivets if I remember correctly - and a couple of screws. The most aggravating part of the process is removing the aero moulding under the doors. There are 7 or 8 plastic rivets under under the car that need to come out and 2 of 3 aluminium rivets under the long plastic cover plate in the door jamb that have to come out. There are also screws front and back.
Disengage the clips holding the under door aero moulding from the front fender. Look between the under door moulding and the fender moulding for an opening. You need to push down on the tab in the opening to release it. I found that using an old table knife worked pretty well. I started at the front and released it then moved to the back. Now, disengage the tab at the back in the same manner. BE CAREFUL! You do not want to break these tabs.
When reinstalling the aero moulding, secure the rivets in the door jamb first, tabs next, and then the screws. Plastic rivets are the last - at least that’s the way I did it.
