66 dart gt drip rail/top trim removal help needed

Yup it sucks!! The first thing I did was make a makeshift hook tool I used a very old steel flat screwdriver, if its not steel its just gonna snap with the new cheap metal. My Barracuda had a butt jointer on both sides of the top rails you need to unclip them first from underneath, then you should be able to gently move your tool down the channel, all this happens underneath you should not go above on the roof side. Its kind of hard to explain I did't take many pictures of that portion of dissasembly. Call me if you have any questions 757-450-4907.
