No worries mate I found it . . . Just concerned I may need to replace the actuator now as the lever has not been returning to centre lately. I thought it was just the gear selector bush that needed cleaning/filing according to others on here. Then there are also some who have had to change the actuator /-: So I'm stuck what to do.
It's the bush on the top that needs opening out, it's swells over time and just becomes stiff, if you open it out to 10mm iirc that should sort it, and should centre again.
