I had three studs broken off and took it to my local repair shop. They replaced two of them with standard bolts and left the third one that was behind the shock tower. He said they just tightened it down real good. Huh, didn't ask about that one. Paid the shop over $600 and was on my way. Two weeks later , the exhaust leak was back. The shop would not stand behind the repair. I ended up taking mine to the Ford dealership (which is where I should have gone in the first place). They had to separate the body from the frame and lift the body up to get to the manifold. I now have everything repaired to Ford specs and she purrs like a kitten. It did cost $1600 though.
