im not going to bother with the sidepanels.. that ebay car that somone posted last week was an SE with front and rear bumper covers from an SLE and it looked good... im thinking itll be too much work to convert the sides aswell.
I believe they are just tape as well. GM didn't want to put holes in the doors if they didn't have to. Why have 2 different doors if you can just tape everything on. I know for a fact that my doors are the same as an SE'* because I was there when they replaced the tape on my RR door trim. When they did it, it was sitting right next to a 2003 SE in the garage that was having it'* tires rotated.
