Right so I had the standard stiff (side-to-side) gearstick.
So I took the linkage off at the gearbox end and replaced the 2 bushes on the pivot, and put it all back together.
Checked the movement of the gearstick, and lovely and free now and even self-centres.
Also maybe related, maybe not, I too the centre part of the dash off to replace a load of blown bulbs.
Anyhow, the problem now is that I can't get 1st gear! It's like you can't quite push the lever forwards enough, and it therefore won't engage. If you push it as far forward as it will go, as you let the clutch up, the stick just pops back into neutral.
It seems I can get all other gears, and it all worked fine before I took the linkage apart
It can't be anything too serious....! Is there an adjustment that needs errm, adjusting?
