bell housing bolts

[siii8873]

I am reassembling my gearbox. I see in the workshop manual that two of the bell housing mounting bolts are "special fitted" bolts and need to be installed opposite of each other. I did not keep track when I disassembled. My thought is that these are two body fit bolts for alignment. I did not remove the top stud & bolt. This leads me to believe that the top bolt (not stud) is the special bolt so the other special (bodyfit) bolt needs to go diagonally opposite this bolt.
Are these assumtions correct?
thanks
