Mike,
From what you've said so far, it sounds almost like you tried to
remove the carridge bolt without removing the bracket from the TB first.
If that's the case, I'm not surprised that the bracket broke. Here's
the deal: (warning, bad ASCII graphics follow!) :-)
-------------------------------------------------------------------------------
Here's a "side view" of the throttle body bores... This is sort've
what it would look like if you were on the driver's side of the engine
bay, looking across the TB.

All you have to do is put a socket on the "Bolt which holds bracket to TB"
and unscrew it. Then the bolt, the carridge bolt, and the entire bracket
will come off of the TB. Now you can hack on it all you want without
worrying about damaging the TB. I used a wrench and a pair of pliers to
take the carridge bolt out of the bracket and replace it with a longer one,
but later I just removed the entire bracket and put an S bolt in. (I
got a piece of (1/4"?) non-threaded rod, bent it up in a vise, then used
a die to tap the ends.) If you were to replace the bracket/carridge bolt
setup above with an S bolt, this is what it would look like:
