The first set of endlinks that I removed came apart pretty easily, so I was surprised when I ran into the same problem that you have...I can't get the endlink off of the body-side mount. Even with the mount clamped in a vice, the whole works just wants to spin. It looks like the steel "liner" inside the bushings has siezed to the shaft attached to the body-side mount. Since I've tried all sorts of penetrant and even soaked it in dilute muriatic acid for 12 hours (great for removing rust!), I guess that heat is the last choice. They don't exactly grow on trees, so i don't want to tear them up too bad... Have you seen this site? Mustang II Tech They have a great bit on rebuilding the rear end links with polyurethane. Apparently a gas grill works well for softening up the factory bushings!
