How did you butch those bolts so bad? Do you not have the right sized wrench?
To get it out, take some old allen wrenches, some 5 minute epoxy, and a dremmel. Epoxy the wrenches into the bolt (simple glue won't work), and just turn them out, then use the dremmel to cut off the bolt and do it again. If that doesn't work, you've probably rusted the bolts in place, if thats the ase, take it to the shop.
