hi,
pull the weather stripping back, under that there are a bunch of screws take them out and the outside c channel will come off, but be sure to pull it slow and a little at a time becaus e there is a foam holding it on good. then one you take that off there is the drip rail chrome, do the same pull the screws and slowly pull the chrome, this has a rubber adhesive backing to it so you might want to heat it up with a heat gun or you wifes hair dryer. If you take your time it should be just fine but be carefull not to bend the chrome. I have another set if it doesnt turn out. just kidding it will be fine! later good luck with your project!
