I replaced my alternator on the side of the road, in the dark last week, and managed to pull a bolt out of the block that I think was not supposed to come out. If you look at this video at the 10.01 min mark, you'll see the alternator nut on the right, and the two bolts at 6 and 10 O'clock positions. I managed to not remove the 12mm nut, but the whole bolt came out. The nut is rounded off and I can't get it off the bolt. So right now my alternator is held in place with just the 2 bolts at 6 and 10. Anyone know the part number for the bolt and nut I removed?
