T56 Bellhousing

2 bolts missing next to each other, another reason for the longer bolts in the trans. 1/2" depth on a 10m bolt is probably just enough to be good enough. If I have 1" of threads I like to use them all. More is better than just enough.

As the holes in the bell, 1 for the hydraulic feed to the bearing, the top slot is for the bleed tube for the bearing, the big hole towards the bottom is for a fork with the slave cyl in the outside of the trans. Two different set ups. That is my best guess.
