Drilled, deburred, clecoed and rivetted all four fairlead mounting blocks.
The two aft mounted blocks required slight rotation on the mounting due to a sidewall rivet that protruded by the block enough to affect how the block's 3/4" hole could be centered vertical's 1" hole.
Drilling out to cleco in place.
Final rivetted in place.
Rotated slightly to center in 1" bulkhead hole (back side protruding rivet interferrence).
