has anyone adjusted there steering box and is it as simple as i suspect, is it the same as any other steering box?

Not too bad.
Engine off (No power steering), raise front wheels off the ground, slacken locknut and turn adjusting screw ,holding driver to get a feel on the screw to nip up . Turn steering wheel from lock to lock making sure there are no tight spots. Tighten up locknut-job done.
Stand back to see if there are any finger marks on the pristine bodywork!!!!!!

so the same as any other then, i take it its got a tapered worm so the adjustment is done with wheels pointing straight ahead! and yes, make sure no finger prints on bodywork, lol......thanks.
