I have. There are 2 studs on the front that are made into the Exhaust manifold. They hold the front just fine. The drivers side on the back needs a short ball stud. The passenger side in the back has some sort of stud and sleeve with a nut on it. I cannot get any confirmation from anyone what exactly that is. I have been to the Lincoln deal to look at a Nautilus, and they weren't any help either. The Ford cover is identical to the Lincoln, it just says Ford.
