Alternator bracket bolts busted in G2500 Van

Don't know how it happened, but when wife called with no steering and overheated van in the local Sam's club parking lot, I found this instead of the assumed busted fan belt. Alternator, tension pulley, and idler pulley along with the bracket were tilted forward a bit. All 3 bolts were busted off, a bit below flush.

Not much room to work with this in a van, but I got about 6 inches or so to work with after pulling various items off. Tried drilling with a portable drill fitted with a 90 degree chuck and a 1/8 left-hand bit, but couldn't get much pressure on it, and the drill would only go

600rpm. Have towed van home so can use a real drill now (faster) although I couldn't find a bigger left-hand bit (wanted to try around a 1/4).

Bolts are soaking in Seafoam deep creep now, and I have acquired a set of Craftsman Drill-out power extractors. Haven't tried these before, but they have a left-hand design on the drill part of the extractor bit. Not sure if I should use cutting oil with it, though.

Looking for any suggestions cause I ain't too optimistic at this point. Even tried to look up a local EDM guy in the phone book, but no luck - dunno how available that is or what it costs, but it's gotta be cheaper than pulling the engine.

Anywho, I got 2 weeks before SWMBO gets home from a trip, and if I don't have this fixed by then my wheels will be taken away!

That works just fine if there is something sticking out of the block or head to grab with the style of extractors you are describing. But if you had read the first post you would have seen he is talking about BOLTS that have sheared off flush, not a stripped bolt head or messed up stud. and the extractors he is talking about from Sears are basically left hand bits for a drill.. Cutting oil will defeat the design which is to start to drill through the broken bolt body and then grab into it turning it out. Also keep the drill speed down.
