Howdy. Snapped off an exhaust stud while replacing the heat exchangers. Going to make a drill guide that will index off the remaining stud so I drill in the center of the snapped one. But I need to know the bolt centers between the two studs. Anyone know that measurement? Thanks in advance.

Bear in mind, even with a drill guide you will probably ruin the threads and have to move up to a step stud. Not a huge issue. Also, make sure you have a drill stop on your bit, and that you really measure how deep you can go. When you tap, you will need the taper or plug tap to get started, but this is a case when you REALLY want that bottoming tap to get the last threads in your bore. Otherwise, you will not be able to seat the last 3/16th or so of your new exhaust stud.
Before you try drilling, have you tried building the stud back up with weld and welding a nut to it? The weld wont stick to aluminum, and the heat from welding will help break the crusty bond the old stud has with the head. Zach |

Zach (IMG:style_emoticons/default/agree.gif) If you have anything of the old stud sticking out, weld a nut on it. I use a gas torch for that. The heat helps break the stud loose from the head. |
