Hi,
As far as the stripped one, do you have access to it? If so, they make bolt extractors for bolts with stripped heads. I attached a pic from an AutoZone site of what they look like below. If you have these, they should remove them.
Now, the one blocked by the frame is a different issue. Is there any clearance between the bolt and frame?
Let me know.
Joe
