How to remove side scoops, A and C pillars?

The piece just above the door glass and goes down to the lower part of windshield has screws under the weather strip. You have to pull out the weather strip to access them.

I believe the rear panels over the rear side glass has screws that you can access when you remove the inner panels that the rear seatbelts go through.
 
i believe the A pillars just stap on/off.

the C--access them from the interior. you have to take the side panels off (both top and bottom... top first) to get to the nuts/bolts that hold them to the car.

same w/ the side scoops--the bolts are behind the interior quarter panel.
 
A pillar- One bolt in the door jamb holds the lower part on. Then you remove the weatherstripping and you will see like an elongated plate with 5 or 6 hex bolts holding it in. Take those off and the plate and you will see like 5 or so philips head screws, take those off and the A-pillar should come right off.

C- pillar- Take off the seatbelt point off with big hex key, or vice grips. Pop off the interior panel and get it out of the way. Then there are 5 7/16th" bolts holding the C pllar on.

Cowl cover- Remove windshield wipers. Remove the hood weather stripping between the hood/cowl cover. Then remove the 3 phillips head screws on the lower part of the cowl cover. Run you hand below the weather stripping which is between the windshield and the cowl cover and you pop the cowl cover up along the whole front of the windshield. All done.
