so, here is the universal steering column joint with the gaiter on for mk1:

blue line is pointing to the pinch bolt. the head looks the same as a regular bolt. do i need a special tool to remove it, rather than standard wrench?
i’ve watched a video where someone is whacking the heck out of the top of the joint, where the red line is pointing. they use a spiked tool of some kind and a hammer to remove the joint.
changed the text in light of a reply
why is the steering column lock secured by shear bolts? why not regular bolts?
thanks
