Hey Brian,
I tried my big adjustable wrench. But no go. I think I'll need a 12 point socket. Wonder why GM used bolts with such strange shaped heads on these bolts. Could've just used bolts with regular hex heads. Dumb!

Spray the threads with PB Blaster and use the flats where it attaches to the frame. They're are screwed into nuts welded to the frame so some heat could help but watch out because PB Blaster and WD40 are very flammable

On mine the holes were threaded AND there were nuts threaded on the bolts. I backed the nuts off of the frame and the bolts then backed out easily with an open end wrench. I think the nuts are supposed to act like a lock down so the bolts don't back out of the threaded holes.
