Dave, there is an alternative to safety wiring the Tension bolts that I use
(learned it from the Racing crowd).  A thin sheet (.025-0.032) of steel can
be cut out to fit inside the lip of the rear housing where the heads of the
tension bolts are.  It goes on before the rear seal flange  (as best I
recall, If interested I'll "refresh" my memory - or perhaps Lynn can better
explain) and they are used to hold the sheet in place.  This sheet then
covers all the tension bolts and should one break it can not back out and
cause more damage.  Easier than drilling 17 of those bolts I think and
cleaner looking.

FWIW
