Mike,
I work in a machine shop and we don't ever use those
extractors. We used to try, but they hardley ever work
you just end up driving yourself crazy with it and the
the little tangs break off. The one that I have used
several times is an EZ out. They work this way if
you've never used one before. First job is to figure
out what size screw you have and then pick the
appropriate EZ Out size. The first job is to then
drill a hole into the screw. Then you hammer the EZ
Out into the hole. The EZ out is essentially a square
plug with almost like a cutting edge on the four
surfaces, then the length of the part is tapered so as
you hammer it in it tightens to the inside of the hole
that you drilled. Then you need an adjustable wrench
to turn the screw out.
I have had a lot of success with this method, not
always on cars either.
Hopefully this will help, if you already tried this
then just ignore me.
