Re: Best method for extracting bolts with broken off heads...
 

I can't believe it, but I think I actually won! I got the last bolt out
this morning, so now I can start re-assembling.

To get the bolt/broken bit out, I ended up taking a punch and driving it in
beside the bit. That let the new bit bite in, instead of spinning on the
end of the other bit. After I got as much of the old bolt out as I could, I
ran a tap in to clean the threads up, and made sure I could get the new bolt
in deep enough to hold things in place. Oh yeah, and to get clearance to
get in there and get things done, I ended up taking off the front of my
truck. FYI, to get that off, you need to take the plastic covers for the
headlights, and the turn signal lights. There are 4 bolts (2 per side).
The bottom two can be reached without taking off the turn signals, but the
top two are covered.

Anyway, thanks all for your condolences, help, and support! You guys make
up a great group! Hopefully the re-assembly will got smoother than the
disassembly, but since I'm using all new parts, I think it will.

Re: Best method for extracting bolts with broken off heads...
 

Glad you finally got it, clint. You may want to get some new bolts. Also be
sure to use anti-sieze on the new ones, and not the cheesy kind! Do any of
those bolts pass into the water jacket?
