Bought a new dark blue top for my 66 dart and thinking about trying to install it myself, how hard of a project is it? The frame is in great condition, and bought new cables and tack strips. Anything to look out for or any special tools required. I know a heat gun is helpful and have one, thinking it does not look to tough looking at the installation instructions. Did buy a canvas top instead of the original vinyl, anything I need to know when dealing with this material?
