My 92 Clan has had it's rear end, 'Dropped' by around 40 mm, by my reckoning. I'd like to raise it back. Is it possible to do this by marking the torsion bars, relative to their mountings, and rotating 'X' amount of splines, instead of using the threaded tool, that substitutes the shock absorbers? Also my outer suspendion arm mounts are showing some quite serious corrosion, are these easily replaced, I know the bushes need pressing in etc...I'd replace them complete. Cheers, Paul.
