[QUOTE="Brian, post: 432527, member: 19943"] Both of mine were broken off, but I had the advantage of needing to pull the manifold off the engine anyway. I Drilled out the first one to 3/8th, but at that point I was able to see the the original studs were a serrated pressed in stud. I heated and drove out old piece which left almost a 1/2" hole. I was lazy and just used a couple of grade 8 3/8" bolts and nuts rather than track down replacement studs. [/QUOTE]
