you need to get a service manual for it. so you can read up on all the body parts.
but there are 2 bolts that are hard to get to, well actually time consuming.
the exterior pillar there is a bolt right under it but covered, so you will need to go inside the car and pull off the leather pillar cover. there are 2 bolts that hold the exterior pillar on, its an 8MM deepsocket once those bolts are off go out side the car and pull hard it will make a clicking sound and pull off.
the second hardest bolt to get to on the quarter is right behind the air vent. you need to reach up above the vent thru the fender liners and turn this star looking nut. there are 2 one on top and one on bottom. then slide the vent housing out. and there is the bolt.
also kinda easy another on under the rocker panel.
then there is one connected to the rear bumper and the rest are visible
other than that there should be no questions on how to remove the quarter.
other than removing the rear bumper but thats easy.
good luck
