or you could drill a small hole into the sheer bolt and use a stud extractor
or just drill the head off as the stud will then unscrew as tension will be gone after that .
just need a mole grip on the stud etc
Removed mine the same way, dremmel a slot, but had to use an impact driver to undo it. My yoke nut needs a 14mm allen key to undo it.
You can't get a pair of Molegrips in to grip it mate.
after you drill the head off the bolt and remove old lock i mean ?
