I have a set of the craftsman ones, I would let you borrow them if you don't mind driving to Indiana.
All jokes aside, the set costs ~$20 and is well worth the purchase, its saved my ass many times.
It has teeth in the counter clockwise direction so it will crab the stripped bolt head.
Depends on how much room you have, in a similar situation a few weeks ago I just pulled off the exhaust and hack sawed the rusted bolts off.

This is a great deal, when i got mine they were $20 and I only got four sizes, this comes with 10.
