If I remember correctly they would be 7/16" x 14 thread pitch and length according to your type mount. Some people hook the engine stand up with to the clutch housing with the clutch,pressure plate and flywheel removed, but I prefer to bolt the stand right to the back of the block. Mount the rotating head of the engine stand to the block and then hoist the block to hook to the stand itself. A word of caution: Inline 6's because of their length can tip an engine stand very easily,especially the 3 legged stand. A 4 legged stand is better. In any case make sure the block is properly supported as you rotate it or move it around. Good Luck with your project.
