I need to know how many bolts hold the carrier together since one bolt fell out and wreaked havoc on my rear and popped a hole in my TA Diff cover.

I have one bolt head that is chewed up and metal shavings all in the oil.
On the Torsen itself there are 4 bolts right now, 2 on each side close together.

so, is there supposed to be 5 or 6 bolts holding the carrier together?

here is a pic from torsens' site,

from this angle, I can't tell if there are only 5 or if there is supposed to be 6 bolts.
