Don't count on this but I don't see any other option than trying to open it by force, even up to the point that the bolt gets cut, if that happens, it should be possible to get access to the other end of the bolt and get it out, either way (which car, if SBC brakes, take care of switching SBC off first).
There are a lot of reports from the same problem but I haven't heard that turning to a case where the bolt cannot be detached. I've had at a few broken when the dealers (yes the dealers, not the tyre companies, those as well as myself always use a torque wrench) overtighten the bolts. Here my experience has been that the bolt is still softer than the base and you could then apply force to remove the bolt, even to the point it gets broken, the bolt I hope.
Also of course better to check the possible damage from the "too long bolt".
