I can believe that.

Actually, I agree. I think the left handed bit is a good idea. BUT, I
have never had that work for me. AND I have never had an ez out work
either. I mean, if the thing is corroded in there enough that you end
up breaking the bolt off, I can't see how the heat involved in drilling
is going to make that much difference (I try using a propane or
acetylene torch when possible - never seems to make a lot of difference
unless you get the stuff red hot, which isn't too useful on things like
cylinder heads and engine blocks :-).
Anyway, maybe you're just luckier than me :-) I try all these things
and end up drilling them out anyway. I keep hoping for a magic bullet
to ease the trauma though.
The last time I broke off a bolt, I had to remove the intake manifold
from my '8 and drill it out (with left hand bits). Then I had to use
a teeny grinding wheel to get the rest of it off without screwing up
the theads. Locktite makes a useful thread restoring compound for
cases like that.
The time before that involved removing the seats on the '8. The seat
mounting bolts snapped off. In that case, I had to end up punching out
the nuts that had been spot welded to the floor and welding in some new
ones. I broke a 3/8 EZ out on one of those.
