Usually drilling would be a good idea but in this case I think it won't work because the danger of drilling too far and ruining the coil over spring setup you have.
What I recommend doing is heat up the bolt head with a propane torch. Then get the next size Allan key and hammer it in hard while the bolt is hot. Let it cool down for like 20mins and then is should be stuck in there enough to unscrew the bolt.
Or maybe
Find a screwdriver attachment (square), bigger than the stripped hex hole, find a drill bit just a little smaller than the hex hole;
drill about 1/8 " deeper, take the attachment, and insert in with a hammer
Get your ratchet set, attach to the screwdriver attachment, and slowly undo the bolt. If it strips again, you'll have to drill it out, then tap and die it.
Sorry this all advise I can give. hope this helpful.
