Lynn, a while back you mentioned safety wire for the exhaust swivel ball, is this in addition to the cotterkeys in the spring bolts, or is it a safety wire to secure the flanges in event of bolt failure or some reason.  JohnD

It is to assure that the joint cannot open, no matter how much assembly is avoided.

 

It is strung through the springs, so that should a spring break, pieces of spring cannot escape inside the cowl to create additional problems.
