Replaced the seals in the clutch master cylinder. AAARRRRGGGHH Got the split pin and pin out without too much trouble after removing the front seats, the column and the heater/air pipes, but I had to make up a special clamp/holder to get the new pin back in and opening the new split pin was a nightmare. The fork needed a bit of welding to make the hole round again. The bloke who put them in at the factory must have been paid well and been a contortionist to boot.
I fit a R clip to the clevis pins for ease of removal
