I second the notion of using inserts instead of helicoils... but what
I'd like to know... from someone who's really in-the-know... would it
be wise to just go ahead and install inserts on the whole arm? Or
should it be only done on those that are obviously damaged or suspect?
I guess, in other words, is an insert better than no insert, in this
application?
