[AT] IH 656

[Cecil Bearden]

I have had good luck with reverse twist drills and also the square 
tapered easy outs.  The screw type easy outs never seemed to work for 
me.   That said I am still trying to get a bolt out of the lower 
radiator support on my 83 FLC 120 freightliner.  The radiator shop tried 
to weld a nut on it to get it out and they just hardened it.  It was a 3 
hour job and that one broken bolt has turned it into a 3 week ordeal.  
It is just too hot here for me to work very long.  It was still 99deg 
at  midnight last night.  It was 97 at 7am this morning...
