Well, to get the hole drilled now, you will need a cobalt bit to drill through the extractor.  The last one I bought was about $10.00 or so.  Then, if possible, find a Snap-On brand extractor if you are not uing that brand now.  I know that they cost more, but they are the only ones that I have not broke.  Craftsman, Napa, Ampro, Pittsburgh, all of them I have broken.  Also, how did the main cap bolt break?  Never heard of one doing that before, was it being loosened or tightened/torqued?  If it was being tightened then I would recommend a ew complete set of main bolts to make sure that none of the rest are weak.

yes, i've seen the cobalt at lowes for about 8bux..but it was for the 1/8 " (x2)...anyways, yea i was checking the clearances on the crank at the main caps using plastic gage when it (the bolt) snapped while i was torqueing down the bolt (at 75lbs/ft.)  the head of the bolt, if it resembles the strength of it, showed a + sign.....not sure what that means, but i know the grade 8 bolts have 6 notches right?  anyways, im frustrated......  _  << this close to being done and ready to stab the motor back in the truck to tighten it up.  >:

Other than the mentioned solution, the other option is to take it to a machine shop.
