The drip rail trim is fairly straight forward. I've never removed the front/rear glass trim but it involves bending the spring clips slightly so they reliece the trim.
To remove the side trim, you need to remove the weather stripping from the channel at the top of the roof. Be careful so you don't tear the weather stripping. The repop weather stripping is expensive and it doesn't fit nearly as good as the original part. Once that is removed, you'll see a bunch of philips head screws that need to be removed. That holds on the weather stripping channel. Once that is removed, you'll see a few screws that hold on the drip rail trim.
There are some foam gaskets between weather stripping channel and the drip rail trim.....as well as bewteen the body and the drip rail trim. The gaskets can make removing the trim a little tricky. Just take your time and don't force them off. New foam gaskets are available from DMT.(Detroit Muscle Technologies)
