Well, very happy to report that we got the broken bolt out. I ran to my local hardware shop and picked up a short 90 degree attachment for my drill and the tight working space, along with a screw/bolt extractor kit. I wasn't so sure about it, and initially it was taking time just to put a mark in the snapped end. Once I put some real force on the bit though, voila it backed the piece right out. Never been so relieved. Keeping the bit as a reminder, it's not always the end of the world.
