Well today I managed to get hold of some replacement driver member bolts. They were a pain to get hold of though as 3 local Landy places (including main dealer!) didn't have any in stock!!! In the end I got some off an old axle one of the Landy garages had laying around :)
So now everything has been rebuilt so let's just hope the lock up problem doesn't reappear!!!
A blog about my 1989 Land Rover 90 (Defender). It's here so I don't forget all the stuff I've done to it and will also hopefully be a help to anyone else with similar issues!
