so my water pump went on the club drive the other day. i was still able to do about half the 5 hour drive, and i had a water pump waiting for me when i got home. so i set to work today to pull it out, got all but 3 bolts out, then i look and see an allen key and i think "thats strange..." so i wip out a 6mm allen key and pop it in there. it has a little flex and then shears off with the end stuck in the bolt. i can't pull it out of the nut, and i can't get the nut out. i need my car tomorrow afternoon, and im not really sure what to do now... anyone got any bright ideas for me?
edit: i forgot to mention it was a craftsmen prof. key, and i'v tried drilling it with a small bit and it just snapped like a tooth pick. i tried low and high rpm's before it broke, and it only made a small pin prick in the key.
