oxy acetylene )
all landrovers should come with the bottles in the back, its by far the best thing for removing anything from a landrover.
With a bit of pratice youd be surprised what you can burn off without touching the surrounding area. you can burn a nut off a bolt and not touch the threads on the bolt Once you get up to it, its the first choice for corroded anything
Brute force and ignorance are my specialities.I would try to break the bolt first with brute force and ignorance, if that fails I would take the dremel to it.
be ok if you get hold of the stuff nowI use oxy acetylene to get it red 'ot, glowing like a cherry and they nearly always come out. If not, they get a blast of oxygen from the torch and it blows then right on out of their stupid hiding place.
Granted, it might ruin the surrounding ali but hey... you bought a Landy
