With vintage muscle cars being 35-plus years old, it won't be uncommon to find the factory rubber body bushings dried out and in need of replacement. As the bushings degrade, the body will slowly sink and the panel gaps will start to change. You could replace the worn components with rubber during your restoration, but those will eventually dry out as well. Luckily there is another option that will outlast rubber and also stiffen the chassis for better handling capabilities.
