catto prop

[n2s3]

quick question guys.helping a friend install a new catto prop which has a extension bolted on the the crank,then the prop bolted to that. there is no provision for safety wiring the bolts holding the extension.this tends to be rather alarming.there Is no way to check for loosening bolts during a preflight because you can't see them. locktite is an option, but would feel better about the installation with .041 wire on BOTH sets of bolts.any thoughts?? thanks
