First, I have a stripped hole where the exhaust stud threads into the head. It's a stock 75 2.0 . The PET manual shows #014 397 9, which is AM8 x 56 (what's the "AM" stand for?) qty "8"ea. It also lists #014 684 1, which is CM9 AX MB x 56 (what do "CM", "AX" and "MB" stand for?) qty "X"ea. ( X ???? ) Are there possibly two different diameter studs that were used on the 2.0? The AM 8 is 8mm, right? If so, is the CM9 a 9mm?
Secondly, is there any reason I should not drill and tap/heli coil the head in place from beneath the car. It's looks do-able as hell but thought I would ask here, first. Thx |

And you can get taps, drills, whatever else you need. I always get stuff in 24 hours from them. |
