[Healeys] Stripped Bolt

Any good mechanical thread repair method will result in a stronger female
thread that the standard hole.  The Heli-coil rep used to do a demo with a
sheet of aluminum and a grade 8 bolt.  He would screw the bolt in the hole,
and strip the threads.  He would then install a heli-coil and screw the
same bolt in and proceed to break the grade 8 bolts and the new larger
diameter thread of the thread repair was stronger than the original bolt.
My advise is get a good thread repair kit (heli-coil, time sert, etc) and
repair the hole, no need to weld it first.
