When I heard the snap, I almost threw in the towel because I thought that the bottom of the bolt was going to be deep in the threaded area. Fortunately and after reading the posts here I realized that on removing the bracket i would be closer to where it snapped and I was...enough that the vise grips just clamped on the bottom of the bolt and took it right out!
So my new concern is...if I put a new bolt in there, have the threads been compromised in any way?
So Stretch...I don't know what to tell you.

It is possible that the threads have been compromised.
Get a new bolt (I'd personally prefer one from the dealer not from the local hardware shop) and try fitting the bolt on its own - remove the bolt and look for any evidence of swarf or metal muck on the threads.
If there's no evidence of thread damage then you should be good.
Test your torque wrench =>
